Mitsuru

Mitsuru (ミツル) is one of the main characters in DARLING in the FRANXX series. He's a Parasite with codename "326" of the Thirteenth Plantation, where he's partnered in boy-girl pair with Kokoro to pilot a FRANXX called Genista. Previously, he was the partner of Ikuno and pilot of Chlorophytum. He and Kokoro share a romantic relationship.

Appearance
Mitsuru is a very clean and proper student with sharp features. Prior to Episode 16 when Kokoro cut his hair, he had slicked back olive hair and piercing deep green eyes. His hair is now shorter and a bit rough-cut. He wears the standard stamen uniform. Standing at 165 cm, he is the second shortest stamen, being between Zorome and Hiro.

Personality
Mitsuru is full of pride and has a strong cynical personality. He hates being pitied and Kokoro cites that he never liked leaning on others for support.

History
As children, 016 gives himself the name Hiro and 015 the name Ichigo. Mitsuru stands with his ball. Other children begin asking for names as well. Though they wait for their parents, they never return to them. Mitsuru shyly asks for a name too. Hiro smiles back at him.

Hiro sits beside her and asks if she wants a name since he gave himself one. He says his name and says she'll feel better if she has a name like him, so he names her "Ichigo." He says that having a name makes it feel okay to be different. She is amazed and asks if he can name the others. He begins naming the other children, including Mitsuru.

Two adults enter and says that they can't change their designation without permission. Hiro politely asks what the problem is. The adults realize he's one of the teens and simply tells him not to just do as he please before leaving. Hiro thinks that they never answered his questions and no other children ever asked any.

As Mitsuru walks off with an adult Hiro asks if he's going to the lab and if there is something wrong. Mitsuru says he's going to get an Elixir Injection, as he won't be able to stay if he doesn't. Mitsuru says he wants to become a parasite with him. He asks if he comes back alive, if he would pilot with him. He happily agrees and the two make a pinkie promise.

After that, their memories are erased. Hiro forgets his promise to Mitsuru and stops naming other children. Zero Two swears to become human since if she were like him, they could be together.

Episode 01: Alone and Lonesome
The parasites discuss Zero Two in the living room. Mitsuru says that Hiro's showing real integrity and that it must be difficult for him, though he says this without compassion.

At Cerasus, the parasites attend their welcoming meeting where they are praised by Papa. In the train, the group discuss Hiro on their way to the startup ritual. At this ritual, they finally become official parasites. Before they can begin, a fog rolls in and a Maho class klaxosaur appears. The parasites watch as Strelizia defeats it. They are shocked when it's revealed that Hiro was piloting it.

Episode 02: What it Means to Connect
The day after the klaxosaur attack, the startup ritual picks up where it left off, but in much quieter circumstances and without Papa and the other adults.

At the dining hall, the parasites watch as Zero Two drenches her food in honey. When Zorome offers to let her ride with him, Mitsuru seems unimpressed. He is confused along with the others when she calls him "darling."

Nana says that she'll be their caretaker, just like she was in Garden.

As the stamen get ready, Mitsuru notices Futoshi eating bread, though he turns away.

The parasites enter their FRANXX. Ikuno pants, though Mitsuru seems unfazed. The four FRANXX pilot, leaving Hiro to train alone.

While Futoshi and Zorome pass a ball around, Mitsuru leans against a pole. Mitsuru says that he heard Zero Two can pilot a FRANXX alone, and asks if they seen its four legged form. He says that Hiro was just taken along for the ride. He doesn't interfere when Zorome and Hiro begin to fight.

Nana calls a meeting and the parasites all attend. They announce that Hiro will have a mock battle, possibly allowing him to be promoted. Though he's about to pilot with Zero Two, Ichigo volunteers instead. Mitsuru asks why it has to be her, as she already is partners with Goro. Mitsuru scoffs when Zero Two isn't allowed to pilot with him.

The parasites watch as the two battle. Mitsuru is surprised when Ichigo pilots alone.

Episode 03: Fighting Puppet
The parasites discuss Hiro's current situation as he's not a Parasite and he could be a burden. Miku accuses Ichigo of being too biased towards Hiro.

Mitsuru says that he understands why she wants to stick up for him, but he was only taken along for the ride. Ichigo yells that they don't know that. Mitsuru says that Hiro was special, even among the double digits, and they were all certain that he'd be their leader. But in reality, he couldn't become a parasite and he isn't what he used to be. He says that they should cut their losses because he doesn't want to see the pathetic side of Hiro anymore.

During a meeting, Hachi says they received sortie orders from HQ. Nana tells them that the Klaxosaur won't be as big as the one they already saw. Hachi says it's a Conrad-class klaxosaur, a bit smaller than a FRANXX. He says that they're attracted by magma energy reactions and appear in their vicinity. He says, lately, they had been showing up deep in a Level 8 mine on the outskirts and wreaking havoc. Nana says that Strelizia won't be a part of the mission. Because they'll have to defend Plantation 13 by themselves eventually, it will show if they can handle fighting them in the future. Nana says that Ichigo and Goro will have field command.

In the FRANXX, Zorome is excited, but Miku tells him not to go crazy by himself again. All but Mitsuru and Ikuno connect. Hachi asks what's wrong, Mitsuru says that it doesn't look like Ikuno can do it. Ikuno says that he's nearly there and to wait for a second. Mitsuru seems annoyed and tells her not to bother. Hachi announces that Chlorophytum will stay behind.

Nana asks if Ikuno is not feeling well. She says that that isn't it. Nana says that she has always been a bit unstable and they'll run test the next day to make sure. Mitsuru asks if it could be that they have compatibility issues. Smiling, Nana says that a lot of parasites experience that at first and it isn't grounds to split them up. Mitsuru seems disappointed.

Zorome tries to check on Miku, as does Ichigo. Many more suddenly fall from the ceiling, so they plan on fleeing. Nana says that they attracted more because they released their magma energy. Zero Two says that she should have sent her from the start. She says they'll die. Hiro is alarmed and tells her to sent himself and Zero Two to help. Hachi refuses and says that he isn't an official stamen, so he can't give permission to board a FRANXX. Zero Two says that the plantation squad is going to be wiped out again and to let her pilot with Hiro. She says she won't be allowed to sortie.

Mitsuru says that he could pilot with her. Nana says that Strelizia is no ordinary FRANXX, if he isn't used to its connect. Mitsuru says that, if Hiro could, there's no way he couldn't. Zero Two says that she wants to ride with Hiro, but he asks that she just go with him. As Mitsuru walks by, he tells Hiro not to come crying to him when he regrets his goody-two-shoes act later because he's going to prove that he can pilot Strelizia better than he did.

Miku wakes up and Zerome hugs her. They begin piloting again. Hachi tells them that Strelizia is about to help. Ichigo is bothered by this and causes them to fall. This lets the klaxosaur to get in, so they flee. Many follow and a very large one is about to bite Ichigo. Strelizia appears and kills some. Mitsuru tells them to get back and Hachi tells them to evacuate.

Panting, Mitsuru says that he feels like he can do anything. He says that he's amazed changing partners could make such a difference, and he knew he wasn't the problem. He says that he's just as good as Hiro. He tells Zero Two that he wouldn't mind becoming her official partner, to the dismay of Ikuno. Zero Two says that she should go all-out for a bit.

Hachi tells her to stop, as the others had already evacuated. The three FRANXX are surprised what happened. Zorome apologizes to Miku. She says that it doesn't matter if it was his fault, since they're partners. He begins crying. Goro asks what's wrong with Ichigo. She lies and says she got careless after she found that help was coming.

When they retrieve Streliza, Zero Two walks out and smiles and waves at Hiro. Mitsuru is gravely injured and unconscious. She says that he isn't suited to be her darling, only Hiro is.

Episode 04: Flap Flap
Shaking in bed, Mitsuru says that Zero Two is a demon. Futoshi walks in and takes Mitsuru's food away. The other parasites wait outside. Futoshi says that he hasn't touched his food at all. Zorome says that he'd been like that since the battle.

Hiro walks in and asks what happened with Zero Two. He says that she tried to completely devour him. Though it was normal initially, she eventually was out to kill him. When Hiro reaches out to him, he suddenly grabs Hiro's collar and says that she had a smile on her face.

Kokoro yells out to Mitsuru and Futoshi tells him to calm down as he hands the tray to Zorome. Mitsuru says that it'll happen to Hiro too, if he rides with her again. Futoshi holds him back and lays him back into bed where he seems to have fallen unconscious and pants heavily.

Hiro bathes and thinks about the rumor. Zero Two appears and says she found him. She walks into the water and rubs his chest. She asks that he run away with her. Seeing her horns, he gulps. She asks if he thinks she's a monster as well. Before he can respond, an alarm sounds.

They detect a worm-type klaxosaur heading towards Plantation 13. Mitsuru tries to get up, but struggled. Ikuno tells him to grab on, and he refuses. Eventually he leans on her anyway.

Hachi says that they've only detected one, but there may be more in hiding. He tells them to connect.

Mitsuru says he hopes Ikuno can connect. She says she can and they connect. The FRANXX advance forward. The FRANXX momentarily stop it, but another one grabs Argentea. Hiro and Zero Two watch and Zero Two says that they should help and asks who landed in the transport plane.

They fly through the air and Hiro is happy to be able to pilot. They discuss their feelings of connection and Zero Two says they're a perfect fit. They zip to where the other parasites are struggling and quickly save them. Ichigo is reluctant to rely on her. When Hiro challenges this, Mitsuru seems offended. Ichigo agrees and tells everyone where to focus. Strelizia rips it from the ground and reveals it was actually one long klaxosaur. Strelizia stabs its core, destroying it. Hachi announces that they neutralized it and to return to base.

Episode 05: Your Thorn, My Badge
Cerasus carries out the kissing with Chrysanthemum. The parasites watch as the plantations connect. Zorome asks what "kissing" is. Miku mocks him, but she doesn't know either. Kokoro points this out. Ikuno explains that it's a transfer of magma fuel reserves from one plantation to another through a large pipe.

Mitsuru explains that the fuel is essential for both the adults and them to live, and FRANXX can't be operated without it. Goro says that, since it's a large-scale transfer of magma energy, it should attract a large number of klaxosaurs. When Futoshi and Zorome seem nervous, Hiro reassures that they have Strelizia, so they'll be fine. Ichigo sadly agrees.

A grand ceremony was conducted with the utmost solemnity. The children of Plantation 26's FRANXX squad were also in attendance, and they seemed a lot more calm and composed that Plantation 13's.

The mayor says that the klaxosaurs are sure to attack in great numbers, and the fate of the two plantations rests on their shoulders. He says they're strong and will bring them to victory.

Kokoro says that the previous day's ceremony was so exciting, she couldn't sleep. Miku says that 090 seemed nice. Kokoro asks if she would like to ride with him. She says that it's better than the boys they're stuck with, and tries to get Ikuno's opinion. Ikuno says she doesn't care.

Zorome happily says that it's heartening to be supported by the adults. Futoshi agrees, and Zorome imitates the mayor's speech, making some of the parasites laugh. He finishes that he'll be the one who leads them to victory. Smiling, Ichigo says that Hiro will. Kokoro agrees and says that he shone in the previous battle. Futoshi asks how he's feeling, and Hiro says fine. Futoshi is happy to hear this, and Miku says that the rumors about Zero Two weren't true. Ikuno says that maybe he's extremely compatible with her, saddening Ichigo.

Hiro thanks them, and says that he had a hard time keeping up with everything happening, but their support let them win. Hiro happily asks if he can let him fight as part of the team. Goro observes him suspiciously.

Zorome becomes annoyed and tells him not to get cocky, since he only got through one time. Goro asks if he has to be a spoilsport. Hiro stands and tells him he'll do his best to not be a burden. He extends his hand and asks that they keep fighting together. Zorome is taken back, but tells him to keep it up as he shakes his hand. As Miku teases him, Mitsuru becomes angry and leaves. Kokoro notices him walk out.

At 7, Futoshi announces that it's breakfast. Zero Two runs over and pulls him away. She sits in Futoshi's seat, to Mitsuru and the other stamens' disdain. Ichigo tells them to take their seats so they can prey. Kokoro invites Futoshi to sit beside her.

Kokoro prays that Papa never thirst and that his heart be filled with peace for eternity. Though everyone bows their head in prayer, Zero Two pours honey over her food. As they eat, Zero Two begins feeding Hiro. Goro looks uncomfortable, and Zorome says that he wants to try something like that. Goro asks why he doesn't ask Miku then. He says that he'd rather ask a cute girl, like Kokoro. He notices that she is feeding Futoshi, to his annoyance. Miku teases that she's too easily influenced. Ichigo looks down into her cup.

In the greenhouse, Mitsuru panicky asks why him and not Hiro as he takes pills. He chokes on them and asks what the difference is between them. He notices that Kokoro was watching him. She says she saw him walk in and asks if he's okay, and says that she wants to help, since he doesn't lean on others. He interrupts and asks if she's pitying him. She says no, but he walks past her and tells her to leave him alone.

Klaxosaurs are detected and an hour later a meeting is held. Hachi explains that there are 100 to 150, and they're expected to arrive at 33 hours from then. He says that 13 will act as back up. Zorome and Miku become annoyed at the other unit as they speak down to them. When Hachi says that Strelizia will be placed closest to the pipe, the other team is horrified.

Nana comes in with Zero Two and Hiro. 090 says that they can't fight alongside Strelizia, since she doesn't care about her allies. She doesn't know what he's talking about. He says that they had a joint operation two years ago where his partner was killed under her fault. Zero Two coldly says that "weaklings die" and that it doesn't matter. He begins to walk closer to her, but Hiro steps between them and promises to keep her from going out of control.

As they walk home, Zorome expresses annoyance at being treated like dead weight. Mitsuru says that they are a makeshift team. Goro stops walking and says that Strelizia shouldn't be part of the mission. Hiro happily replies that they should show them what they're made of. Zorome agrees and tells Goro not to be so timid. Goro asks what Ichigo thinks and she says that they need Strelizia in the next battle. When he looks at Hiro, he notices Zero Two glaring at him.

Episode 06: DARLING in the FRANXX
A large Klaxosaur approaches with an arrival time of 0210 hours. Nana and Hachi stand in the control room. Hachi says that he never saw a large klaxosaur like it before.

The stamen walk through the hallway. Mitsuru says that they can't afford to be too optimistic, given the difference in numbers. Zorome says that he is on their side, so it should be fine. Futoshi says that, Zorome aside, they've got Strelizia. Annoyed at his comment, Zorome says that they won't let squad 26 hog the glory. Mitsuru says that shouldn't be why they're fighting.

Ichigo tells him that the operation starts late at night. They make small talk about their sleep before Hiro says they should make sure the operation succeeds. He says that being a leader isn't easy, but he knows she's up to the task and that he's counting on her. She says she counts on him lots too. Zero Two walks by and stops briefly before continuing. Ichigo says that she always thought of him as a brother. He agrees and says with Goro too. He pats her on the shoulder and encourages her as he runs to Zero Two.

In their FRANXX, Hachi announces that, beside from the Conrad-class pack, they've also detected a large, tightly packed unit. He gives 090 field command. He tells Strelizia to stay back.

Unit 26 takes out a few klaxosaurs. 090 tells them to deal with them calmly. Four get through and he asks that Squad 13 takes care of them and advises them.

The stamen comment on his attitude and Mitsuru agrees that they are really new to it. As battle begins, Argentea crashes into Chlorophytum causing Zorome and Mitsuru to bicker. Though Genista is almost attacked, Delphinium jumps in and kills the klaxosaur. Kokoro thanks Ichigo. Ichigo asks Zorome to bait the enemy without getting too close, since they're fast. She tells Mitsuru to stay close to Genista and back it up. Goro advises that she doesn't get too worked up.

Seeing Ichigo, 090 wonders what such a skilled teen code is doing in a makeshift team, along with Hiro. He is interrupted by the announcement of a second wave. Strelizia moves out and quickly defeats many klaxosaurs. 090 scolds her for ignoring orders. Hiro sasy that he's just there to help his squad. Though he begins to protest, Hiro hangs up. A member of his squad asks what to do, and 090 says to ignore them and take it out in one fell swoop. They begin attacking together.

Zero Two and Hiro begin to disconnect, so she turns to see him panting and clutching his chest. She asks if that's all he has. With blue veins popping out of his face, he sits up and she praises him. They continue to fight. Ichigo tells Strelizia to go back, but Hiro says it's fine. She says to get back again, so Zero Two calls her bossy.

Unit 26 begins attacking and the klaxosaur screams before becoming its Gutenberg-class humanoid form. 090 orders them to keep attacking, but they are roughly thrown into the ground. He orders them to get back, but he is unable to move as they're out of fuel. Before they are crushed, Argentea pulls them away.

Hachi orders all squad 26 units to fall back and Squad 13 will deal with it. Though the group agrees that they need Strelizia, Ichigo orders that they stay put. She says it'll land the finishing blow. Zorome becomes angry, but Goro says that only Strelizia's spear can reach its core, so they'll make an opening for it. Ichigo privately thanks him for his plan. They begin crawling up it.

Hiro pants and Zero Two asks if it's too painful. She says it won't end until they kill it. He begins fighting and they launch into it. Hiro things they got it, but it swipes them far away and changes form again. Hiro becomes unconscious. Their link is broken and Strelizia enters stampede mode. It continues to smash them against the wall.

Ichigo breaks down and disconnects from Goro, thinking he's dead. The other parasites worry and Mitsuru says it's bad if it breaks through the wall. Crying, Ichigo says that she couldn't tell him not to pilot. He angrily tells her to get it together.

Hiro stands where he sent Naomi off, realizing he died. Naomi appears and scolds him for giving up without listening to his partner. She asks if he's okay with that. Smiling, he says he doesn't care since he got to be of use. She calls him a liar as the elevator door closes.

Hiro sees Zero Two standing under a mistletoe tree. He thanks her for everything, but she sadly walks away.

He wakes up to see Zero Two struggling and that they didn't actually kill it. He thinks that she can't do it alone. He realizes that she fights alone after losing her partner. He says that his wings exist for her as his veins retract.

He hugs her from behind and she calms down. He says that he's her partner and he won't leave her alone. They begin fighting. They all begin attacking again to create another opening. Strelizia flies into its core as everyone watches in amazement.

They walk out together and the two groups celebrate. As Zero Two watches, she says she has to kill more klaxosaur.

Episode 07: Shooting Star Moratorium
After the successful kissing with Plantation 26, Unit 13 was given a special vacation. The kids seem happy and Futoshi and Zorome run to the water. Though Miku says that they're childish, Kokoro smiles and says that it's expected, as it's their first time seeing an ocean that's okay to swim in. Ikuno says that she didn't know a place like that survived on the surface.

Goro sets up an umbrella and tells Futoshi and Zorome not to go too far out. Ichigo tells him that Nana will pick them up the next morning. Goro wonders if it's some kind of training, but Ichigo smiles and says that they should enjoy themselves anyway. Goro blushes and agrees, turning away.

Zero Two pulls Hiro to the water. Kokoro smiles and says she's glad he's all better. Goro says it's good that he's an official parasite now too. Ichigo narrates that she was uncomfortable about Zero Two, but could see that she was what he needed.

Ichigo watches the other kids. Ikuno smiles and asks if she's distracted by the water. She asks if she is going to swim since she was always good at it. Ikuno pulls out a book and tells her to enjoy herself. She thanks her and runs off.

After Ichigo leaves, Ikuno begins to read. Mitsuru asks if she came there just to read. She says that she isn't interested in goofing around. Mitsuru says that the guy who looked suicidal now looks like part of the group. She tells him not to look to her for affirmation, since she's not like him. Smirking, he says he was merely talking to himself. She asks if they're done talking then, and he says that he found something odd.

Mitsuru leads the group through a thin pass. Zorome says that it's exciting to explore. Kokoro says that she's a bit scared of the dark. Mitsuru coldly replies that she didn't have to come if she didn't want to. Futoshi is angered by this and tells him to be nice to her. He says that he can't guarantee their safety.

Goro asks if there's a relationship closer to being partners and that watching him and Zero Two makes him wonder. Hiro says he doesn't really get it either. He mentions his relationship with Ichigo and thinks he's different than them.

Ichigo looks down as she walks down the path. Ikuno touches her cheek and startles her. She asks why her face is all red. Mitsuru says that they can see it now.

They're lead to what appears to be a city. Zorome comments that it's nothing like the cities that adults live in. Kokoro asks if people live there, and Mitsuru replies that he'd never heard of anyone living outside the plantations. Zorome spots a building that looks similar to their own boarding house. Ikuno says that they must have used it as a model to build the environment they live in. Futoshi wonders where Kokoro went.

Kokoro looks around and comes by a medical office. She finds a book about childbirth. Mitsuru calls out to her and pulls her back before a bookcase falls on her. He asks her not to run off alone.

They walk back to the rest of the group and Miku says that she's exhausted. Kokoro agrees. Zorome wonders about the city and Ikuno says that they can be sure that it was part of civilization. Goro asks if people lived there in the past. Zero Two answers that they abandoned it and that humans used to live on the surface. She says that there are tons of places like that around the world.

Back at the beach, food had been delivered. They all begin eating and Goro hands Zero Two a shish kabob. Zorome roasts a marshmallow. Zero Two tells Hiro that she's going to go swimming before running off to the sea. Mitsuru watches Futoshi stuff food into his mouth. Miku teases Futoshi and Zorome by lying on Kokoro's lap.

Hiro asks why they think humanity abandoned the surface and wonders if humanity hadn't started extracting magma energy, if the klaxosaurs wouldn't have showed up. Mitsuru asks if he's doubting Papa and the rest. He says that they moved into plantations in order to protect mankind. This pumps Zorome up, to Mitsuru's disdain, and Futoshi as well. Zorome asks if he agrees and when he shyly answers, he asks why he's acting so aloof when he's their teammate. Miku says that they have to put in both his and Naomi's share of the work. Kokoro says that she finds it reassuring that they're with them. Futoshi and Goro agree. Ichigo stands and officially welcomes him and Zero Two to the squad. He thanks them all.

When Zorome finds a crab, Futoshi wants to eat it. Mitsuru is surprised that he still wants to eat, causing the others to laugh. Zero Two watches this from the water.

The parasites all sleep close together, with Futoshi and Zorome lying atop one another. Ichigo lies awake in her sleeping bag. She sits up and finds Hiro getting up.

Episode 08: Boys × Girls
As the parasites are fighting a klaxosaur, it spews goo. It leaks into the cockpits and melts the girls' parasite suits. Unlike the other boys, Mitsuru shows no interest in looking at Ikuno. Though the other boys begin spacing out, they don't tell the girls. Hiro finally tells Zero Two and the rest of the girls realize what's happened.

The girls cover themselves with a towel and glare at their partners. Besides Zero Two, who doesn't seem to mind. The boys look embarrassed, besides Mitsuru who seems to not care. Goro explains they only didn't tell because they didn't want to distract them during the battle. Futoshi says he didn't because he found Kokoro to be amazingly beautiful. Kokoro turns red and looks away. Mitsuru calls him an idiot and walks away, and Ikuno watches him leave.

The girls split the area of the house between the boys and girls. Zorome begins to cross, but is threatened by Miku and stops. Mitsuru again looks uninterested, but watches nonetheless. Throughout the rest of their feud, Mitsuru does not get involved. Neither he or Hiro go swimming to mock the girls, and he eats without acknowledging their argument.

When Kokoro enters a small greenhouse, she finds Mitsuru. He slips his medication into his pocket and she asks if he has an interest in plants as he tucks a baby book into her own pocket. He says no, and that it's a good place for being alone. Kokoro says she begged Nana to let her take care of the greenhouse. She tells him about the meaning of some of the flowers and then asks if he doesn't mind chatting with her when the girls and boys are "feuding." He says it's stupid and can't be bothered. Kokoro is amazed and says it takes a lot of courage to refuse to toe the line and she was too scared to say anything. When he walks closer to her, she panics and drops her book. He says that it doesn't matter to him and walks out.

When Zero Two changes the girls only bath sign to allow boys, Mitsuru enters along with the rest and find that the girls are already bathing. They become angry and begin throwing bathing supplies at them. Zero Two runs out with their clothes and Hiro chases her. Mitsuru again doesn't get involved as they throw things back and forth, sitting alone at the side of the bathroom.

The other parasites continue to bicker when Nana suddenly interrupts. She and Hachi scold the group after they get dressed. In the boys room, Zorome is mad and Mitsuru says that they must look down of the boys. Hiro says it was fun and got to see a more human side of Zero Two. Mitsuru says it's not the same for them, since they have normal partners. Hiro says she is a normal girl and that pistils let stamen handle all the controls, but they bear the brunt of each battle.

After Miku hides, the rest find her and wonder what the room is. Zero Two says that it's probably one of the rooms the former Squad 13 used. Zorome questions what happened and Zero Two says they were obviously wiped out.

Each partner apologizes, except Mitsuru and Hiro. Mitsuru briefly glances at Ikuno, but walks away without saying anything. Ikuno seems to understand his response and begins to smile.

Episode 09: Triangle Bomb
The parasites are happy to receive their gifts: Mitsuru receives a pen. Zorome shouts that he'll read Papa's message. The parasites smile as he reads it out loud. The letter congratulates and praises them, making everyone happy. Hiro notices that Zero Two is unfazed by the letter.

Hachi tells the parasites that they've detected a Gutenberg-class Klaxosaur 2,000 from there. Nana says it's moving slowly. As she continues to talk, Hiro looks over at Ichigo but turns away when she looks at him.

The FRANXX approach the klaxosaur and Argentea approaches first. It is wrapped in tentacles and brought closer. It attaches explosives, which causes slight injury. Mitsuru notices the core and quickly charges at it. He only nicks it and it begins to multiply its jelly. Goro quickly pushes them out, but is stuck instead. Goro quickly launches Ichigo before it explodes.

Goro wakes up and turns off the alarms. Hiro begins messaging him. He says that Ichigo's fine but got knocked out by the ejection and is getting treated with Zorome and Miku. Hiro explains that he's inside the klaxosaur. They were ordered to retreat. Futoshi promises that they'll figure something out. Goro says that he's switching to safe mode to conserve power.

Ikuno says that you can't utilize a FRANXX's magma energy without its pistil. Mitsuru says that they are programmed to run their life support systems on backup power. Zero Two says he'll die if it runs out and they'll all be in danger.

Ichigo suddenly charges in with Miku and Zorome following. Though Miku tries to stop her, Ichigo asks what happened. Zorome says he told her that he tried to save them. She turns and asks why they aren't going to rescue him and how they could abandon him. She asks why he'd cut her loose when he's helpless alone. Zorome becomes uncomfortable and backs away from their argument. Miku sighs and calls her annoying and says that Goro's always looking out for her, like the time Hiro almost died when she broke down and Goro got her back on her feet. Ichigo asks what gives her the right to talk to her like that. Miku says that she's supposed to be the leader, but she loses her cool and lashes out constantly, and Goro must have a hard time with her as his partner.

Nana and Hachi enter and, smiling, Nana claps her hands and says that she's glad they're safe. Hachi explains that the klaxosaur vaporizes its bodily fluids to expand and explode. Kokoro asks if Goro's stuck in its fuel. Nana says that the fluid is harmless to FRANXX. Zorome says that they'll rescue Goro first, since he owes him. Hachi coldly says that their top priority is preventing the target from making contact with the plantation and explains their plan. Hiro angrily asks if they'll leave Goro to die. Nana says that if worst comes to worst. Hachi tells them to prepare to sortie. Ichigo asks to speak to Goro.

Goro says it's been 30 minutes since they radioed. Sweating, he tries to loosen his collar. In his hand, he holds Ichigo's hairpin. Ichigo calls out to him and he is happy that she came to. She suddenly shouts, scolding him, but he smiles. She sadly asks why he doesn't lean on her a little. Crying, she promises to save him. He says he came up with a plan and he's going to kill it and come home to her. He says he needs to go to conserve power.

Ichigo asks Hachi to be allowed to save him. Hiro agrees. Nana asks what they intend to do. Zero Two says that there's an exhaust hole on top of the klaxosaur.

Genista and Chlorophytum stand as the last line of defense. Ichigo sits in Strelizia's hand. Hiro says that, to get to Delphinium, she'll have to cross an area of highly pressurized vapor fuel. Zero Two says she wouldn't do it if she was her. Smiling, Ichigo says she believes in her. Zero Two smiles and says she doesn't dislike that. They throw her in and she swims to Delphinium.

Inside, Goro pants. He remembers two kids asking why he always picks fights with them. The other says he's weak, so it doesn't matter. Goro says he was sick of the communal lifestyle and thought he'd get to be alone if he made everyone hate him. Ichigo asks why he keeps getting into fights when he's so weak. He tells her to mind her own business. They push him to the ground. She helps him up and they defeat the other kids together. She says they can win together. Goro smiles and thinks that he loved her since then. Hiro suddenly walks in and smiles at Ichigo and the kids all stand around him. Goro notices she is overjoyed to see him as well. Though he looks sad, he narrates that it was okay because Hiro was special to him in his own way too.

The klaxosaur approaches the line. Goro thinks that he used to think that he didn't mind if his feelings never got through to her. As Ichigo swims, her hair clip comes off. At 6%, Goro says that he has more than enough to self-destruct, and an extra pack. He says he wishes he could have told her. Ichigo suddenly bursts in and says that the air's thin. He asks why she came, and she says he's so headstrong, even though he's weak. She says that they can't win alone, but together they can. Goro smiles with tears in his eyes. He narrates that he though he was satisfied that she would cry for him, but he's happier than ever to see her smile. He extends his hand to her. They leave and Goro drops the bomb, causing it to explode once they're away from it.

Ichigo bandages him. He asks where her hair clip is. She looks around, distressed. He hands her his and she asks if he picked it up for her. He says that he waned to give it to her, but couldn't. Smiling, he says that he loves her. He says that he doesn't want to regret not taking action. She smiles and thanks him for being her partner, but she doesn't know how to respond to his love. He says he wasn't trying to put her on the spot. They hug and he asks if they can stay like that for a while.

Episode 10: The City of Eternity
The FRANXX attack a klaxasaur and easily disarm it. Zorome and Miku deliver the final blow, but Zorome takes too long to pull out and it shoots blood all over Argentea.

Zorome and Miku argue about their previous battle. Hiro notices that Zero Two seems sad, so he asks her what's wrong. She replies that she was just thinking about something and they both leave together. Nana shouts that she has good news.

The parasites gather around her and she happily explains that they have to wear their formal clothing the next day as Papa is going to award them medals. The ceremony will be held in the Plantation Parliament HQ. Though the other kids are excited, Zorome doesn't understand and seems indifferent to the medals. Miku explains that it means they can go into the city. Zorome looks to Nana for confirmation and she smiles. He becomes overjoyed and yells, to the annoyance of Miku.

Zero Two looks indifferent and turns to leave. Before she can, Nana stops her and says that she'll arrange for her to undergo tests while there. Zero Two says that she hates the tests and always feels lousy after she takes them. She turns and smiles, saying that she's in great shape right now and will pass on the tests for a while. After she leaves, Nana says that she thought she'd grown more obedient since she teamed up with a certain someone.

The next morning, the kids stand at the door and they remark that Zorome looks cooler than usual. Zorome smugly agrees, but Futoshi teasingly says that he was checking himself out in the mirror the entire morning. Mitsuru asks how he didn't get sick of it, causing Zorome to become angry. Kokoro giggles and says that he does look a lot cooler, though, returning him to his positive mood. Miku tells Kokoro not to flatter him, causing she and Zorome to bicker again. Hiro notices that Zero Two is being standoffish, but Hachi and Nana open the door and they all leave.

At an ID gate, Hachi and Nana easily pass through. The children hesitate so Nana tells them to come along. Zorome suddenly throws himself through the gate, to the amazement of the others, but lands on the ground.

The children marvel at the city. At the ceremony, the mayor congratulates them and thanks them for their efforts. When he congratulates Ichigo, she says that it was everyone's effort. He tells Zero Two that their plantation is honored that a former Nine like herself has joined them. He turns to Hiro and says that he's lived up well to the expectations placed upon him. Hiro thanks him, but looks troubled and turns to Zero Two who still looks indifferent.

He thanks Miku and when the mayor thanks Zorome, he is overjoyed and offers his hand. The mayor seems confused and walks away.

Afterwards, Zorome stares at his hand. When Hachi says that he's leaving the rest to Nana, the children are disappointed with how the ceremony actually played out. The girls push Nana to let them walk back, and she reluctantly agrees.

The children look around as they walk back. Zorome happily looks forward to when they too can live there as adults. The others disagree and feel like they won't be able to become adults, though they don't know why.

Zero Two and Hiro walk far behind the group. Hiro asks what she meant when she said the city was lifeless. She says just what I said. Hiro says that she'd been acting weird, and asks if something happened. She says that she just couldn't care less about this place.

The children marvel at the city's main energy source. When Goro asks Ichigo, she seems uncomfortable. He says that maybe he shouldn't have told her how he felt and says to not let it bother her.

Nana tells them they have to return, but Zorome wanders off and is separated. He looks at the energy source, but realizes that he's been separated and cannot contact the others.

Ichigo happily announces that they found Zorome and everyone sighs in relief. Miku calls him a jerk for making them worry. She sentences him to clean the bath for a week.

Episode 11: Partner Shuffle
Smiling, Hiro tells a group of children that he's been chosen to represent them. They stare back in admiration. Present-day Mitsuru tells himself to stop looking at him with admiration. He shouts that he's a traitor, causing him to wake up.

Zorome notes that it's unusual for him to sleep in and Futoshi asks if he was having a good dream, as his face is all red. They head off for breakfast as he rubs his forehead. He narrates that he chose to not expect anything from anyone, preventing his hopes from being betrayed. He slips out of bed and leaves the room.

Ichigo reports that they killed 25 conrad-class klaxosaurs. Nana thanks her and says that the S-Planning in their area is proceeding smoothly, thanks to their efforts. Hachi tells codes 326 and 196 that they need to improve their kill count, and that their parasite score is dropping as well. Hachi dismisses the group, leaving him and Nana alone.

Hachi notes that they've now killed over 90 in their area. Nana smiles and says that their kills over the past fortnight are 3.7 times greater than in their first. She says that what would normally cause problems in a group are drawing out their full abilities. Hachi says that it would be a total refutation of their previous methods. Nana replies that it might be what Dr. FRANXX is after.

As the unit stands on guard, Zorome asks what "S-Planning" is. Hiro replies that it seems like they're digging for something, and Zero Two says that it's probably nothing good and she can smell klaxosaurs.

Futoshi tells Kokoro that they've grown stronger, as they're on a special mission. Kokoro says that it's thanks to him carrying her through. Futoshi says that she's his responsibility and she giggles and thanks him. Blushing and nervous, he asks thar she promise to be his partner forever. She again smiles and agrees. Futoshi is happy and promises to always protect her. Miku suddenly interrupts and says he's gross. Zorome agrees and says to cut off his comm. Kokoro giggles, but Futoshi reprimands them for listening.

An alarm suddenly sounds and Ichigo announces that seven conrad-class klaxosaurs are approaching. Goro wonders if they have a nest nearby. Ichigo tells them to get ready. Chlorophytum suddenly falls to its knees. Ikuno turns to see what's wrong, and finds Mitsuru sweating and panting.

As Mitsuru lies in bed, Hachi notes that his child fever came sooner than expected. Nana gives him an antipyretic as Hachi notes he had already had the procedure.

Goro notes that he had always been frail, and Ichigo adds that he was the only one who received the injection and came back. Miku is confused, so Ikuno says that it was the Elixir Injection, a highly concentrated drug that induced yellow blood cell production and greatly increases parasite aptitude. Miku asks if he had always acted that way. Goro says no, he used to follow Hiro around. Futoshi says that that's shocking and Zorome asks how they ended up butting heads. Goro says he doesn't know, but it started not long before he took the injection. He says that Hiro changed a little back then, too. Kokoro says that the injection has only a survival rate of 15% and didn't know he had such a risky procedure.

While dreaming in the hospital bed, he remembers telling Hiro that he wanted to be like him, fight in the FRANXX together. He sadly says that he can't because he's too weak, so if he takes the injection and comes back alive, he asks if he would pilot FRANXX together. Before he replies, Mitsuru suddenly wakes up, cursing.

The next morning, Nana notes that he seems to be out of the woods for now. He asks to pilot a FRANXX. She is reluctant and thinks it over. When they test, his capacity is low and Hachi notes that he might become a pruning target. Nana thinks of what they should do.

She suggests that they try a "partner shuffle." She tells them that it's simply an option available to them. The children discuss their thoughts, and Futoshi says that they don't need to, since he promised to protect her forever. He asks if she agrees and she reluctantly agrees. Hiro asks Zero Two if something is bothering her and asks if she remembers when he asked her to speak her mind with him because he wanted to get to know her better. As he talks, she covers his mouth and says they can understand each other just fine by piloting Strelizia together.

Mitsuru watches Hiro from far away and Ikuno tells him to stop, since he knows what caused the mess. He asks what she's talking about. She tells him to drop the act and that it takes courage to face up to others and himself. He asks what her point is, and she says that he wants to be acknowledged, not by Papa or the adults. He suddenly shouts for her to shut up. Everyone turns to look at him, causing him to look ashamed. Ikuno smirks and says that it suits him better than acting cool and aloof. She says she's not like him.

Nana asks if there is anyone who wants to try piloting with a different partner. Ikuno asks to try a pistil-pistil connection as a backup plan when they've lost a stamen. She asks Ichigo to help. Ichigo is surprised by reluctantly agrees. Nana agrees to let them try and asks if there's anyone else. Kokoro shyly puts up her hand and asks to try with Mitsuru. This surprises everyone, and Futoshi is hurt. She apologizes, but he begins to cry.

Nana announces that 160 seconds have passed. Ichigo says she doesn't feel anything and they time out. Genista's score crossed the minimum required, though it is in the lower range, it is stable.

In the locker room, Ichigo smiles and says she knew it wouldn't work without a boy. Ikuno coldly says that she was serious before closing her locker and walking out. Both she and Mitsuru leave at the same time. She tells him to laugh if he must.

Futoshi cries into his pillow as the other boys are at his side. He asks if he did something wrong. Zorome suggests that maybe he annoyed her and that he should lose weight. Goro wonders why she would and Hiro replies that she must have felt she had to do something for Mitsuru. Zorome smiles and says especially since he's so miserable. Futoshi leaps out of bed and begins shaking him, saying clearly he's the most miserable. Goro tells him to calm down, as Mitsuru suddenly returns. They all turn to look at him. He begins to leave, but Futoshi angrily asks if he thinks he's pathetic. Mitsuru asks what it matters who their partners are. Futoshi easily throws the others off of him and says he has no idea how he feels. He tries to punch him, but misses and falls on his face. Mitsuru adjusts his tie and says he's annoying. Hiro tells him to try and understand Futoshi's feelings. Mitsuru clenches his fist and asks what right he has to say that. Hiro doesn't seem to understand and Mitsuru walks away. On the floor, Futoshi says that, when he thinks of Kokoro, his chest feels tight. Now, he says that the tightness hurts now and wonders why. Hiro smiles at him and says he understands.

In the greenhouse, Kokoro twirls around and hums. To her doll, she says that the flowers smell nice. Mitsuru suddenly asks what she's doing, and she throws her doll in surprise. They sit together and she asks why he thinks humans stopped having children. He says probably because they don't need to anymore. She says that it seemed having a baby was the most natural thing. He tells her not to waste time thinking about unnecessary things, as one look at the adults makes it clear: They don't need others to live. He asks why she volunteered to be his partner and that Futoshi hates him now. He asks if it was out of pity. She says no, and begins to suggest something, but is interrupted by sirens.

A Gutenberg-class klaxosaur approaches and Hachi commands to set up a defensive line 500 meters from the S-Planning and neutralize the target. He says that Genista and Chlorophytum will act as rear support. As Kokoro and Mitsuru go to their FRANXX, Futoshi stops him and tells him to protect Kokoro. Mitsuru scoffs and says not to be ridiculous. Kokoro stops him and says she'll be fine. Futoshi tells her to be careful and says he'll do his best with Ikuno. Kokoro smiles and nods. Futoshi begins crying and rushes into the cockpit, causing Ikuno to sigh.

Zero Two suddenly attacks, and Hiro says that its core is too deep. She rushes in again and is trapped, forcing Miku and Ichigo to save her. She tells Ichigo to mind her own business and charges at it again. The pieces cut off turn into the Conrad-class klaxosaurs they'd been fighting. Before she can attack again, Hiro stops her and she tells him not to get in her way. He asks Ichigo what they should do. Kokoro says they need to shoot at it. Futoshi cries as they talk.

Three get past and Futoshi goes after it. He tells Ikuno that she's too tense, but they manage to kill it. Mitsuru struggles as well, and Kokoro says that there's no need to rush. Strelizia kills it for them and Hiro asks if they're okay. Kokoro thanks him, and he tells Mitsuru to hand in there before rushing back. Mitsuru becomes annoyed and charges blindly at the klaxosaur, causing them to smash into it. An operator announces that Genista's positive pulse is dropping below minimum. Though they are about to be squished, Chlorophytum protects them. Ikuno asks if they're okay. Kokoro thanks both of them. Miku and Ichigo cuts its back legs, but it begins stretching in place towards the S-Planning. Ichigo says she and Miky will stop it. Miku tells Chlorophytum to take care of Genista. Futoshi says that he'll protect her as they shoot into its foot.

Kokoro says that they should start over and turns toward Mitsuru. They power down and he tells her that if she places her hopes in him, she'll only be let down because he's incompetent. She disagrees and Hachi suddenly orders them to reconnect. She enters them into radio silence, leaving Hachi confused. Kokoro says that he can rely on others more and that she believes in him. She tells him to believe in her too. He smiles and asks if she's joking.

As a child, he asks Hiro to pilot together. Hiro smiles and promises. After his injection, he approaches Hiro, who forgot all about it. He tells Kokoro that believing in someone will only get you betrayed. He says he was a fool for expecting anything from him and asks why he would make a promise if he was going to forget about it. He holds his head in his hands and cries.

Kokoro says that must have deeply hurt him. She says that she acted similarly towards Futoshi and she isn't the nice girl they think she is. She says that if someone did something like that to her, she wouldn't have any right to complain or blame them. He angrily asks if he should forgive him, then. She says that they aren't perfect like the adults, but she wants to have relationships. She says she believes in him. She turns and begins to enter stampede mode. Mitsuru suddenly hugs her and she stops. He asks how she can trust someone so much. They smile at each other.

Genista reconnects and they all work together to kill it. Afterwards, Futoshi asks why he was so reckless, and Kokoro is about to stop him but Mitsuru stops her. He punches him in the face and Kokoro rushes to care for him. He asks why he didn't dodge it. Mitsuru asks if he realizes how unreasonable he's being. Futoshi shouts at him before Mitsuru slowly says that he promises to protect her. Futoshi falls to his knees and says that he loved her. Hiro sadly looks on from his FRANXX and Zero Two embraces him from behind. She tells him that they'll be together until they die.

Mitsuru reflects that he doesn't know if he can forgive Hiro, but he agrees that he knows things will keep happening between them all. The next morning, his temperature returned to normal.

Episode 12: The Garden Where It All Began
The episode starts with the members of Squad 13 looking out of a large window within a vehicle, seeing the Garden as they approach it. Zero Two is elsewhere within the vehicle, looking for picture books but to no avail. Squad 13 has been sent back to The Garden to undergo some tests, the place where they were raised. They are greeted by the Nines, Zero Two's former squad, and their leader Nine Alpha who wonders what Zero Two, formerly coded Nine Iota, saw in them. Disobeying orders, Hiro, with the other members of Squad 13 visit the old facilities where they were raised in, hoping to meet Naomi again. Naomi is nowhere to be seen and the adults refuse to tell them where she is. They also discover that the children from Garden are being developed into Parasites at a much earlier age, in response to the increased number of Klaxosaur attacks. When a group of Klaxosaurs attack the Garden, Squad 13 is dispatched, and Hiro notes that Zero Twos canines and horns have grown longer. During the battle, a hysteric Zero Two ignores direct orders and attacks alone, claiming that she must kill more Klaxosaurs in order to become truly human. After the battle, Hiro asks the meaning of her words, but she refuses to answer. Meanwhile, Ichigo eavesdrops on a conversation between Nana and Hachi in which they affirm with each other that the Saurification process in Zero Two and Hiro is intensifying, much to her horror. When the second wave of the Klaxosaurs attack, Squad 13 sorties again and once more Zero Two turns rogue. Hiro is attacked by Zero Two whilst trying to stop her, and he receives visions of a past long forgotten.

Episode 14: Punishment and Confession
Zero Two and Hiro realize they knew each other as children. Zero Two catches Hiro before he collapses and asks if he's her darling from her childhood and is horrified thinking of what she had done. Ichigo suddenly interrupts and throws her off of him and into Goro. He asks if she's alright as Ichigo tries to revive Hiro. The other FRANXX wait. When they return to the docking facility, Hiro is taken for treatment. Zero Two realizes what Hiro meant when he said he wanted to understand her better.

At an APE hospital room, Nana notes that his yellow blood cell count has gone far beyond what the human body can handle and his saurification could begin at any moment.

Zero Two goes to talk to Hiro, but is stopped by Ichigo. She blames her for his hospitalization and says she can't see him again. Goro and Miku tell her to calm down. When Ichigo reveals that Hiro will lose his humanity, the rest of the parasites don't believe her and ask Zero Two. She tells them to shut up and mind their own business. Ichigo stops her again from seeing him and says that she isn't a member of their team.

Hiro wakes up and is surrounded by his teammates. He asks where Zero Two is and Ichigo says she stopped her. Hiro has strangulation marks on his neck. They all leave, but Hiro stops Mitsuru.

Hiro says that he made a promise to him before he got an Elixir Injection. Mitsuru is surprised, but says to never mind and it was a long time ago. He says he'd forgotten about it before that. He says that any other stamen would've died long ago. He tells him to listen to Ichigo and stay away from her. Hiro says that he has something to ask her and thanks Mitsuru.

He says that after that day, his aptitude kept decreasing. Though he felt like he died, she gave him a new life. He thinks it must be because he drank her blood. Zero Two sits in her room, biting her nails.

Hachi announced they must neutralize every klaxosaur inhabiting Gran Crevasse. Nana says that it is a joint operation with the 9's and FRANXX squad from each plantation. He says that Squad 13 is schedules to be part of the sixth wave. Nana says it will be their most difficult mission and Ichigo raises her hand. She asks that Zero Two is removed from Squad 13 as of that mission and, if not, Squad 13 will not participate in the operation. Nana says that she was set to return to the 9's as of the mission anyway. Zero Two protests, but the parasites stop her from seeing him.

When Hiro gets up, he is stopped by Miku. Zero Two is also guarded and prevented from leaving her room. Ichigo comes in to see Hiro and they chat. She gives him an apple. She tells him that Zero Two is returning to the 9's the next night. She asks if he hates her and says that, even if he does, not to go anywhere.

Hiro apologizes and Ichigo cuts her thumb, so Hiro bandages it for her. Zero Two remembers what Ichigo said and thinks that she knew she could never be a human. Ichigo leaves the knife and apple peels. Zero Two breaks out of her room as Ichigo returns. She roughly throws Goro against a window. Ichigo scolds Zero Two and asks if she wants to lie to him again. She says she's wrong and just wants to talk to him.

Goro tells Ichigo to let her see him and Kokoro agrees, stating that it's sad to see them apart. Goro says that she can meet him, but they're all going to be there. When they enter the room, it's empty. Hiro had used the knife to make a rope out the curtains. He then tied the knife to it and climbed upstairs, escaping containment. Zero Two becomes enraged and says that they tricked her. Hiro unknowingly goes to Zero Two's room.

He asks through the door if she knew about their past. He opens the door to find the room destroyed. He returns to the hospital to find all his teammates unconscious and her attacking Ichigo. Zero Two, with a devious grin, invites Hiro to "talk lots and lots". Hiro scolds her for being such a monster. She realizes the damage she'd done to him.

Zero Two leaves the plantation as the other parasites watch her leave silently. She passes by Hiro without saying anything. When Ichigo suggests they go inside, she finds that he's crying. He is about to go after her, but Ichigo stops him, saying he'll turn into a monster. When he turns away again, she grabs his face and kisses him.

Episode 15: The Bird that Shares Wings
At Cerasus's international briefing room, Hachi explains that their objective is to take control of Gran Crevasse. Though another group is attacking, they aren't making headway. Squad 13 is to group up with squads from other plantations.

Kokoro asks what Gran Crevasse is. Nana shows them a video where a large amount of klaxosaur are. Hachi explains that taking over Gran Crevasse is Papa's long-standing wish and would be a turning point in humanity's history. On screen, a large group of FRANXX walk behind Strelizia in it's stampede mode.

At APE central HQ on Cosmos, Dr. FRANXX meets with the council. He finds that Zero Two devoured all of her stamen and he calls her a hellcat.

One of them says that they may finally get their wish if they take over Gran Crevasse. Another says that Hringhorni's construction is proceeding smoothly. One says, if they have both, they can bury "those pests" once and for all. One happily exclaims that the time has come.

Dr. FRANXX begins to walk off, and is asked where he is going (referring to him as "Werner"). He says he wants to watch it from a front-row seat.

Hiro watches Zero Two attack a klaxosaur. Ichigo suddenly grabs his hand and squeezes, but doesn't look up at him.

The parasites of Chrysanthemum struggle against the klaxosaurs large numbers. 090 screams when one of his squadmates is almost killed. Strelizia kills it, saving the FRANXX, and 9'α appears to take out more of them. He compliments 090 saying he did well for humans. He says they'll take over, so they can go in the rear.

In Cerasus's command room, they receive a message from mission command saying they're prepared to sortie. Nana tells the kids to get ready. The parasites all walk away to battle. Goro tells him not to be sad, because they'll be fine. Ichigo says that she'll teach him how to pilot from the ground up once she gets back. He asks them to come back alive, and they smile at him.

The 6th united FRANXX company begins marching together. The 9's take out a bunch of klaxosaur. Ichigo is amazed, saying it's like having a bunch of Strelizias. 9'α says that there's a lot of them. 9'β points out Plantation 13 fighting. He jumps behind Ichigo and says that her FRANXX is adorable. She sarcastically thanks him. He says that they're holding them off fine, but they're not making any progress and that the Crevasse has been sealed off inside a thick dome. They need to strike from the inside to get rid of it. Hiro sadly watches from the control room.

The unit takes out many klaxosaurs and Unit 26 notes that they're fighting well. 090 notes that they're still all over the place, but he's happy they're there. He tells them to regroup. They are about to enter the hole in the wall, but the klaxosaur all flee. The control room detects magma energy readings underground ascertained to be super lehmann-class klaxosaur. Dr. FRANXX walks in and is amazed that it was hidden underground. Hachi says he never heard of that class.

As it comes from underground, it pushes the plantation on its side and it begins to break. 090 reacts in horror as his home is destroyed. Vice Chairman says to get 090 on the line and tells him they're moving to Protocol 32. He tells him that it's a great honour. The klaxosaur moves toward plantation 13. Unit 26 lines up with bombs. He whispers that they're counting on 13 now before the squad explodes. It stops, but its face smashes through the wall and it releases klaxosaur inside. Zero Two runs in and begins attacking. The adults say that they have to neutralize the Super Lehmann-Class and Papa and the rest will take care of Gran Crevasse. Nana says that Dr. FRANXX should return to HQ and Hiro to Misilteinn. Dr. FRANXX asks if he finds her more beautiful than any human, pure, proud, and more alone than anyone like a klaxosaur. Hiro says that she isn't a klaxosaur. He says that he thought she had finally found a partner and Hiro goes up to Misilteinn.

The FRANXX struggle against their large numbers. Zero Two takes out a large amount of klaxosaurs. 9'β says that she's in a foul mood. 9'α says that the though of getting on that unseemly beast's bad side gives him the chills.

In Zero Two's room, he finds scratches and blood on the wall. In front of the window, he finds Naomi's mirror, which Zero Two taped back together after breaking it. Gulping, he asks himself why he's holding back.

Kokoro says that they're being pushed back. Chlorophytum runs out of ammo, so they use a pillar to attack. Argentea is pushed back, and the Old Woman watches it walk forward from her window. Ichigo watches Strelizia and Goro tries to get her to focus. They notice a training unit zip by them, as does Argentea. They realize it's Hiro. The training unit is taken out, so Delphinium stops him and says that he won't let him see her. Goro suddenly stops. He says he can't stand watching Hiro and Zero Two like that anymore. He steps out and tells Hiro to get in. He says that Hiro has something to say and Ichigo is worried about her too, so he asks her to take him to Zero Two.

Hiro apologizes to Ichigo and they begin to connect. Finally connecting to him, Ichigo is disappointed to find that all his memories are of Zero Two. She cries as they head out. Smiling, Goro quietly wishes them good luck. Argentea picks him up and Zorome and Miku ask what he's asking so cool for.

Zero Two thinks that, though she pretended, she wished to become human. Ichigo charges towards her. She begins attacking and says that she's sick of how she always toys with her. After Strelizia breaks her spear, Delphinium slaps her and says she wishes she'd never known her. She breaks her helmet and Ichigo says to get her act together as she headbutts her.

As the door opens, he finds that her horns have grown and branched and her eyes are red. He says that he came to see her. Ichigo says to protect Strelizia since it's the only one that can kill the monster.

As Genista and Argentea attack klaxosaurs, one of the cores crack in half and something falls out of the center. Ikuno says it looks like a human. Suddenly, there is an explosion. As it is announced that the backup plan is almost complete, Papa says that they can let the plantation go now. The stamen of the plantation are confused as to why they're making in plantations self-distuct. 9'ε and 9'a says that they're planning to end things without Strelizia's help. Dr. FRANXX is disgusted with their choice.

Hiro tries to connect, but he gets no response. He holds her horns and asks to be taken to her. A man says that, though 016's memories were erased, 002's couldn't be completely erased. The doctor tells them to continue to try and erase, regardless of the effects on her and orders Hiro back to the garden. He says that he's probably useless now that he ingested her blood.

She cannot remember things, but begins to when she recognizes familiar actions. She licks her wounds in a similar way. Seeing her book, she begins eating it. She learns the word "boku" and Zero Two, and "darling." She remembers him getting attacked and begins crying.

Zero Two's horns break and Hiro hugs her. She pushes him away and tells him not to look at her. They apologize and cry holding each other. He says they can see the world together and kisses her as she cries. Strelizia is attacks and transforms into a red version of it and easily takes out the klaxosaur. They confess their love for each other. Futoshi and Zorome cry and Ichigo says she's happy for them. The 9's begin attacking as well. The sages say that the door to Gran Crevasse has been opened and the day of humanity's liberation is upon them.

Inside the mountain klaxosaur, they find that its core is a collective mass of cores. A large hand suddenly shoots up from the ground. 9'a laughs and says that it reacted quickly. It smashes a majority of the plantation, leaving mistiltein.

Episode 16: Days of Our Lives
Futoshi says that, in the battle of Gran Crevasse, their plantation was left in ruins, but they're still living in Mistilteinn. They stand by and wait for their next mission. One month has passed since they were given those orders. He says that the damage to the plantation has affected the water supply system, and they had to restrict their electricity usage. Their caretakers are gone too. Though food supply is delivered once a week.

Mitsuru and Hiro inspect Cerasus' water sources. Mitsuru says that it's turning foul as well. Hiro says they should try and filter it. Mitsuru says that their water supply could stop at anytime as he stands up. They're interrupted when Zero Two bangs on the pot and says that breakfast is ready.

Ichigo serves up their rations. When Zorome complains, Ichigo takes his rations and says he doesn't have to eat it. Ikuno enters and offers to help, but Ichigo says that it's fine and asks if her fever went down. Zero Two places her forehead on Ikuno and says that she's 36.7 degrees (a normal body temperature) but tells her not to push herself.

They pray for Papa before they eat, though Zero Two eats anyway. Zero Two lists off the chores and Miku, smiling, notes that she's meticulous.

As the stamen eat, Futoshi stops. Hiro asks if he's okay. Futoshi lies and says he's dieting. Zorome laughs and pinches his stomach, saying he isn't cut out for it.

Mitsuru went to the greenhouse and asked Kokoro to cut his hair. She was confused, questioning where that request came from but upon seeing Mitsuru timidly look down, she merrily accepted. As she cuts, Mitsuru wondered what he was hoping for with Hiro. He admitted that he was wrong and was probably using his grudge to carve out a niche for himself and now he has nothing.

Kokoro tells him to look up and giggles when he looks. He asks if he looks weird, and she says he looks handsome. She says that, if he understand, he can start over.

He smiles and says her saying that makes him feel like he can do anything, she's kind and gifted with her hands. Kokoro gets down on her knees and kisses him. Mitsuru is quite surprised and does not say anything. Kokoro, embarrassed, apologizes and runs away.

The parasites meet in their living room and Ichigo says that they have five sources they can use for drinking water. Mitsuru says that only two of them are only usable with filtering. Ikuno asks if they can repair the circulation system themselves. Hiro says that Mistilteinn doesn't have the equipment. Futoshi says that their access to the elevator is restricted too. Zorome asks why they don't send a letter to Papa and ask him to fix it. Goro says that he doesn't think there'd be a point. The parasites sadly reflect on their vulnerability, so Zero Two says that they should cook their own food.

Hiro agrees with her, and Mitsuru agrees with him, remarking how there are cookbooks in the library. Kokoro says that maybe they could do it then. They all agree, except for Zorome who pouts.

When Futoshi starts a fire, he tries to show Zorome. Zorome asks if he's not dieting. He eventually becomes enthused as well. Miku and Ikuno make dough. Kokoro makes a salad and Mitsuru reads a cooking book. Ichigo welcomes Hiro, Goro, and Zero Two back from fishing. Zorome and the rest are impressed with the 11 fish that she caught. Goro caught 9 and Hiro, awkwardly smiled and scratched his head, saying he didn't catch any. Zero Two says she'll teach him later. The others want to try fishing as well.

Goro asks Ichigo how she is, and she says that the mood really changed. She happily watches as Zero Two tells the rest how to fish. Ichigo says that Hiro was right about her being a normal girl. She says she wants whats best for her and Hiro.

Before they eat, they all marvel at how they were able to cook. Though Ichigo's about to pray, Zorome starts eating and says why should they when they did everything themselves. He says it's good as Miku tries Kokoro's salad. When she says it's good, Kokoro is happy and she and Mitsuru smile at each other.

Zorome is happy at what they've accomplished and tries to get Futoshi to eat. Futoshi accidentally drops the food and Mitsuru asks if he's okay. As he picks glass, Zorome tells him to quit forcing himself. Zorome begins helping. He says that he knows Futoshi is forcing himself to eat and throwing it back up. Though Futoshi denies it, Zorome grabs his collar and begins crying. He says he has to eat to survive. Futoshi forces himself to eat and Hiro puts his hand on his back.

Zorome asks why Papa isn't getting in touch as he cries. Miku begins crying as well.

Mitsuru says that as pilots, there's a limit to their lives. Miku cries as she says that she was worried too, but too scared to speak up. Ikuno and Goro agree. Goro says that he'd been writing to Nana and Hachi to let them know how they're doing, but they never accepted them. Hiro says it's fine if they were cast aside by Papa as long as he's with them and there's more to their lives than piloting. Futoshi starts crying and says he's hungry. They all laugh and Zorome says he suits being fat.

Episode 17: Eden
9'α, β, γ, δ, and ε stand at the door. Ichigo asks why they're there. 9'α says they came to check on Papa's orders and that he had been worried sick about them. This is a great relief to Zorome and Miku. 9'β notes the problems in their environment and 9'γ agrees. 9'α asks for them to ready rooms for them. Ichigo is surprised that they intend to stay there, and he smiles and says that he'd taken a liking to them.

Ichigo is surprised to hear that all the surviving squads had been gathered in one place and sadly asks why they were the only ones left out. 9'γ says that it wasn't what Papa wanted and that Hachi and Nana should have told them about it.

Miku cries while eating, and 9'δ asks why. Smiling, she says that she's just relieved that they weren't left there to die. Zorome throws his arm over 9'β shoulders and encourages him to eat, though he politely refuses his offer.

Ichigo says that she assumed that they were there to take Zero Two back. 9'ε laughs and says they aren't her babysitters but her squad mates. Even though she didn't seem pleased to see them.

9'δ looks through the hallway when she almost bumps into Kokoro. She holds her before she falls and asks if she's okay. Kokoro thanks her and asks what she's doing. She says exploring and asks that she doesn't tell the others. She agrees to and bows after saying goodnight. On the ground, she notices her baby handbook.

Kokoro brushes Mitsuru's hair in the greenhouse. She says that, since the nines are there, someone should be coming to get them soon. Mitsuru says that he'll be a bit sad to leave, since they only began spending time together after he came there. She smiles and begins patting his head. She slides her hand down the nape of his neck, to his confusion. She says that his body is much tougher than a girl's. She rubs his chest and says that boys and girls have such different bodies, and there's a reason. Mitsuru asks what she means. She says she read that boys and girls can create new life by joining their bodies together. She gulps and undoes his shirt, saying that it represents hope for them. He shoves her hand away and stands, asking what she's doing.

Before she can explain, Zorome asks if they just tried to stick their bodies together and if they're imitating Hiro and Zero Two. Mitsuru zips up his shirt and asks if he needed something. He says that he was supposed to be on water duty. When he asks again what they were doing, he says he'll get the water. He stomps off saying to hurry up then. Mitsuru asks why she did that out of nowhere. She says she'd been thinking about it for a long time.

Mitsuru stands motionless at a body of water. Hiro appears and they enter the water together. Mitsuru says he doesn't understand what Kokoro's thinking. Hiro smiles and says that he's changed. Before he'd only distanced himself from them. Though Hiro says that it was all his fault for breaking their promise. He says that he's probably in love with Kokoro, since he has similar feelings for Zero Two as he does for Kokoro. Mitsuru thinks to his self that he is in love with her. He says he can't be sure, but that it how it's for him as he stands up. Mitsuru stands as well and says that he's similar to Hiro and he's glad that he could have a nice chat with him after so long.

When Hiro and Mitsuru enter the living room, Miku says that he's there. Smiling, Ichigo says that Zorome told them about him and Kokoro. Ikuno says that she's not surprised. Zorome angrily explains that he just asked if a boy and a girl getting all clingy was the cool thing to do. Miku tells him to be quiet. Futoshi suddenly grabs Mitsuru's collar and asks if they'd kissed. Kokoro looks down, embarrassed, and they realizes they had. This upsets Futoshi and begins to say that, if they're happy but is interrupted with the 9's entering the room.

9'α holds up the childbirth handbook and asks if they recognize it. With Kokoro and Mitsuru's reaction, he says that they do. He asks for an explanation from Kokoro, since she's the one who dropped it. He says that it's strange, since it wouldn't have been provided in the study there, and it doesn't belong to her. Kokoro apologizes for not telling them all.

She turns to her squad and says she wants to make a baby. This confuses the other parasites. 9'α smiles and says that Papa had banned that. Zorome says that it sounds bad and Goro asks Mitsuru if she said anything, and he fidgets uncomfortably.

Kokoro turns back to the nines and asks if it's so bad since it's how all humans were born. Futoshi asks if Papa didn't create them. She says they were born like any other animal and it had always been like that for all living things. She says that's why they have boys and girls. She says that she wants to leave something behind before she's gone. She happily explains that their purpose in life isn't just to ride FRANXX and that they could carry new lives and leave them for the future. She says that it made her happy to hear that, but she is interrupted by 9'a calling her disgusting. When she turns to him, he says that she's disgusting.

He explains that humans have evolved and cast their reproductive functions aside in the process. Reject that, and they all have to go back to conforming to one gender. He asks if gender isn't just a pain that's tolerated to operate the FRANXX. Kokoro has tears in her eyes and Mitsuru begins to say something, but Ikuno suddenly walks up and slaps him. 9'γ whistles and the other nines seem surprised, as is Ichigo. Ikuno asks what it matters if it's a pain. alpha says that humans have also cast away their tendency to be ruled by emotions like her since it serves no purpose. He smiles and tells them to look at themselves, though.

Ikuno begins to walk up to him, but is pulled back by Goro and Ichigo. Nana and Hachi appear and ask them to stop.

Nana exclaims that this is why she didn't want to let the nines in. Hachi calmly says that Papa sent them, so they couldn't just turn them away. She says that they should put an end to their test now. Kokoro asks what she means. Hachi says that it was on Dr. FRANXX's orders that they didn't contact them over the past month and that it would be their final test. Though they still monitored them, and know what she was trying to do with Mitsuru. Nana says that no one can speak of that, let alone do it. When Kokoro asks why they have organs for reproduction, Nana says to pilot the FRANXX. She asks what her feelings are for then. Nana has a blurred flashback and then swipes at Kokoro before clutching her head. She tells her to be quiet. Hachi tells her to return to her dorm and they'll give her her orders in time. Kokoro runs out of the room.

Mitsuru sits alone in the greenhouse, thinking. In the living room, Futoshi says that Kokoro is taking a long time to return. Miku says she had no idea she was thinking about that and wishes she would have told her. Ikuno looks down and says that everyone has things they can't talk about. Miku asks if they think they really can make babies. Zorome says he has no idea and Goro wonders how they were born if Papa didn't create them and asks what Hiro thinks. He says he doesn't know, but that they may have the potential to do something Papa hadn't told them about. They reflect that they may be able to leave something for the future. Smiling, Zero Two says she's envious, since she can't leave something behind. She calls them all wonderful since they have the ability to decide their futures themselves.

Mitsuru leaves the greenhouse and finds Kokoro crying on one of the beds. She says she was wrong and apologizes for trying to force him to go along with it. He tells her not to and says she wasn't forcing him to do anything. She says he's lying and tells him not to try and be nice. She asks that he leave her alone. As she walks out, he grabs her arm and refuses. He pulls her into a hug and asks for her to lean on him more because he wants to make her happy. She asks if it was so bad to create a new life and if they aren't allowed to think of the future. He kisses her and she pulls him closer to her. They are later shown to be lying naked in each other's arms.

Episode 18: When the sakura blooms
In episode 18, Kokoro and Mitsuru had a out-door wedding and are now currently newlyweds but were quickly detained by the 9's and brainwashed on Papa's orders. They are later reincorporated back into Unit 13 with no recollection of their past memories.

Hiro
In the past, Mitsuru strongly admired Hiro and his ability, citing that they thought he would be the one to lead them and thought strongly of Hiro as a rival. However, as the years went by and his abilities decrease, Hiro's image in his eyes deteriorated to the point where he found himself unable to stand the sight of it.

In Episode 03, when Delphinium, Argentea and Genista are in need of assistance fighting klaxosaurs, he suggests that he go with Zero Two to go save the others, as he was the only 'stamen parasite' there, and because he believed he could pilot it because Hiro did. After successfully connecting Strelizia and piloting it, Mitsuru boasted about how he could pilot it without fainting, unlike Hiro, and tried to take over as her official partner until he gets injured and passes out by the end of their mission.

In Episode 11, it is revealed that the reason why Mitsuru looks down on Hiro with anger and disdain goes back to when they were children: Hiro and Mitsuru used to be close, up to the point that Hiro promised Mitsuru to pilot a Franxx together. However, unbeknownst to Mitsuru, due to Dr FRANXX memory erasure, Hiro forgot his promise and Mitsuru became affected by what he perceived as a betrayal. The pain of Hiro having forgotten his promise had caused him to present, as described by Ikuno, "a cool and aloof" persona as opposed to his joyful nature he displayed when he was a child, and also caused him trust issues with the group. The latter shows more poignantly when he was paired with Ikuno, causing them to underperform when piloting Chlorophytum.

Zero Two
In the aftermath of Episode 3, he becomes fearful of her, stating anyone who willingly wanted to pilot with her was insane. It was not known what actually happened to him, but from his prospective she tried to 'devour his body, blood, and soul'. And while she was doing it, she smiled. This traumatic experience has haunted him strongly, but he has managed to recover.

Kokoro
Similarly to the rest of the parasites, Mitsuru is quite harsh or cold towards Kokoro. Futoshi scolds him for taking a harsh tone towards her. Later that day, he saves her from being crushed by a bookcase. He formally calls her Kokoro-san. Mitsuru tends to have random walk-ins with Kokoro inside the greenhouse, which she takes care of. It has also been hinted that Kokoro has feelings for Mitsuru. In episode 11, Mitsuru realizes that Kokoro is an unbelievable girl, since she risked her health and strength to pilot Genista alone. In a good way. And for the first time, Mitsuru is worried about his partner, who was now Kokoro. Soon, he promises to Kokoro's former Partner to protect her whenever they ride Genista together. He has shown quite a bit of interest in her, as they kissed in episode 16. Mitsuru also admitted he was in love with Kokoro and the two of them slept together at the end of episode 17. In episode 18, Kokoro and Mitsuru had a out-door wedding and are now currently newlyweds but were quickly detained by the 9's and brainwashed on Papa's orders. They are later reincorporated back into Unit 13 with no recollection of their past memories.

Ikuno
Ikuno is Mitsuru's former partner. Though they don't typically get along, Ikuno seems to understand him better than the others, realizing his feelings toward Hiro.

Futoshi
Initially, Mitsuru and Futoshi are normal squadmates. After the incident of swapping partners in Episode 11, Futoshi is angry towards Mitsuru for not protecting Kokoro when they rode in Genista together, which started the conflict between the two.

Etymology
Mitsuru's nickname may use some of the numeral's readings from his real name "326": mi from 3, tsu from 2 (ツー) and ru from 6.

Quotes
"I say Hiro's showing real integrity. It must be hard for him to face us after what happened, too. Spare a thought for how he feels."

- Mitsuru

"Sure, Hiro was special. Even among the double-digits, he was a cut above. We were all certain that he'd be our leader and show us the way. But reality had other ideas. Hiro couldn't become a parasite. He's not who he used to be. We must give up and cut our losses. I don't want to see this pathetic side of Hiro anymore."

- Mitsuru

"I promise to protect Kokoro from now on."

- Mitsuru

"Doesn't it scare you?"

- Mitsuru

"You're unbelievable."

- Mitsuru

"I understand... I love Kokoro."

- Mitsuru
