Miku

Miku (ミク) is one of the main characters in DARLING in the FRANXX. She is a former Parasite with the codename "390" of the Thirteenth Plantation, where she's partnered in boy-girl pair with Zorome to pilot a FRANXX called Argentea.

Appearance
Miku is a petite girl with auburn red hair and sea blue eyes. Her hair is done up in girlish pigtails, more commonly referred to as "twintails", with a small cowlick at the top of her head. She wears the standard Pistil Parasite uniform and when piloting Argentea, Miku wears a white bodysuit with pale pink accents.

In Episode 16, it is revealed that she has begun sprouting some gray hair on the top of her head.

In Episode 24 when she has become an adult, Miku leaves her hair untied and her hair is seen reaching her lower back. She has a few gray hair-strands on some places on her hair. She also wears a matching pink necklace together with Zorome.

Personality
A beautiful, spunky girl who boasts style at the seams. She appears to have a bright and innocent exterior, but she has a tendency to be selfish in order to sway situations in her favor. Miku is very stubborn, expressive and outspoken, and is not afraid to bluntly state her opinion about something, even if it might be hurtful. This is seen when she openly criticizes Ichigo's faults as a leader and her skepticism towards Hiro and Zero Two, and is unapologetic about speaking her mind.

Miku also refers to herself in third person, which gives her a "cute" impression.

History
Like her other unit members, Miku grew up in the Garden. She has been friends with Kokoro since childhood, and as a child, she was seen making her a flower crown. She receives the name "Miku" from Hiro at some point

A few months before the start of the series, she is sent to Cerasus to become a Pistil and is partnered with Zorome.

Episode 03: Fighting Puppet
Inside, Futoshi asks what happened with Hiro becoming a parasite. Ikuno says he could only connect for a bit at the start, so she doesn't like his chances. Zorome says that there's no way he'll get in. Mitsuru says that he doesn't know about the ones who only managed a draw against that, either. Zorome says that it was Miku's fault for randomly falling over. Miku angrily asks if he remember what he said when that happened.

Kokoro warns them not to fight because it will affect their numbers. Ikuno says that she doesn't think Papa will accept a parasite who can't pilot. Futoshi agrees and says that so many kids disappeared from the Garden due to that.

Miku says that Ichigo is no better. She says that she's too biased towards Hiro when she's supposed to be their leader. She says she doesn't understand how Goro's putting up with her as her partner. Ichigo asks what Goro has to do with it. Goro also walks in and asks what they're talking about. Annoyed, Ichigo says that, if Hiro becomes a parasite, he'll be a great help. Miku says that he might not even. Ichigo says that he still has a chance, and Miku disagrees. She says that he couldn't get it done with her, so I think it's over for him. She says that he piloted Strelizia, even if he was unconscious, and saved them, so she still believed in him.

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.

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.

The three head out to a big hole. They marvel at it and say that they use the pipes to extract magma reserves. Hachi tells them to head down to the 8th floor. He says that, in order to completely neutralize a Klaxosaur, they must extract its core, and shatter it using their customized magma-energy weapons. He tells them to defeat it and the three head in.

Ichigo says that they have visual on klaxosaur and they're spreading out. They run to it and begin slashing it. Before Zorome can finish it, it attacks and knocks them over. Miku is electrocuted and passes out. Futoshi shoots and exposes its core. Ichigo stabs it.

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 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.

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.

Gorilla marvels at Hiro's ability. One notes that Zero Two's search for a man has finally ended. Marmoset says that she still needs to be monitored closely. Papa says that Plantation 13 is a top-priority surveillance subject. He says that Code 016 is tasked with bringing her to the Grand Crevasse.

Hachi says that one of APE's special forces has become a plantation's exclusive parasite. Zero Two tells Dr. FRANXX that they didn't have to come all the way. Nana introduces Hiro to Dr. FRANXX, the creator of FRANXX. She begins to introduce a boy, but he stops her. He approaches Hiro and says that he's the first person to survive Zero Two. He says that he has an interest in them. Hachi tells the doctor that Strelizia and Code 002 are transferred into Plantation 13's purview. He waves at him and says that the geezers already told him. When Hachi announces that they're officially partners, Zero Two hugs Hiro.

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. 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.

They're lead to what appears to be a city. 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.

Back at the beach, food had been delivered. Mitsuru watches Futoshi stuff food into his mouth. Miku teases Futoshi and Zorome by lying on her lap.

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. When Zorome refers to Hiro as their teammate, Mitsuru looks annoyed.

When Zorome finds a crab, Futoshi wants to eat it. Mitsuru is surprised that he still wants to eat, causing the others to laugh.

The parasites all sleep close together, with Futoshi and Zorome lying atop one another.

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. Though the 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, and Goro explains they only didn't tell because they didn't want to distract them during the battle. Zorome tells him that it's not like it hurt them to be seen, and Hiro says that Zero Two said it is better that parasites are a bit pervy, which Zero Two confirms. This annoys the girls further.

As the girls shower, they discuss what happened and wonder how long they had been ogling them. Kokoro says they're taking things a bit too far, but Miku says that should quit.

The girls begin splitting the area of the house between the boys and girls. Zorome begins to cross, but is threatened by Miku and stops. Dr. FRANXX and the two apes watch. Hachi says that it's unprecedented for so many members of a squad to hit puberty at once. He tells Nana and Hachi to observe and write for him detailed reports and to not interfere or tell Papa and the rest.

The girls talk about what's happened but notice that Zero Two is ignoring their split. As they go to reprimand her, the boys walk in from swimming in the lake wearing only boxers. Though Miku tells them to get dressed, he says they can do whatever they like on their side. As they clean the bath, Ichigo says that it must have been Goro's idea.

When they go to eat, the boys are already there. Goro says that they've already taken over the area. Miku becomes annoyed, so Goro suggests that drop all the rules and eat together. Zero Two walks in and Miku attempts to follow her, but the other girls pull her back.

Miku, Ichigo, and Ikuno look for food and go to the first floor. They find a room that says "keep out." Ikuno says she wouldn't mind if it was always sealed off. Zero Two licks her and says she tastes a secret. She begins to walk away, but Miku asks whose side she's on. She says she'll play along. She changes the girls only bath sign to allow boys and, when they enter naked, 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. They meet on the roof where Hiro begins laughing after she throws their clothes in the air. She says she wanted to take part in a human fight.

The other parasites continue to bicker when Nana suddenly interrupts. She and Hachi scold the group after they get dressed. In the girl's room, she tells them if they half-ass things, they'll end up adults. She says to say what they want because they'll all die sooner or later. 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.

Kokoro says that they need to begin working together again after looking at her book. She says that they need them to pilot the FRANXX and, blushing, having children. Miku says she's she'll continue no matter what and heads into one of the sealed rooms. There, she finds a picture of another group and panics. 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.

Zorome apologizes and says he won't leer anymore. Miku says that she's too cute, so a little bits okay. Each partner apologizes, except Mitsuru and Hiro. Later on, Zorome and Miku are seen bickering before they enter their FRANXX. Hiro says that he wants get to know Zero Two better. She tells him to grab on and never let go of her,

Episode 10: The City of Eternity
Zorome narrates that he'd been having the same dream over and over again where he's surrounded by darkness and staring at a distant bright light, and crying. Gradually, the light grows larger until it envelops him, and he lets out a loud scream.

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.

The Seven Sages discuss the children. Tarsier suggests that they reward the children, and Papa agrees.

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 honoured 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.

Episode 11: Partner Shuffle
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.

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.

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.

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.

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.

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.

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.

Zorome
Her partner in the Franxx, she often stands up to him and comments on everything he does with a hint of snark. However, she tends to go along with him whenever he does something and does have a sense of compassion for him despite not openly showing it as much as he does in Episode 3. Despite certain disagreements between them while controlling their Franxx in the first episodes, they managed to understand and work together and control their Franxx better in further episodes.

Hiro
She doesn't seem to think as highly of him as the others once did, commenting on his lack of ability openly.

Zero Two
She seems rather put-off by Zero Two's eating habits, even going so far as to bring up her horns and not refer to her as a person. However, after Zero Two reverts back to her original personality and becomes more accepting of her fellow comrades; Miku grows closer to Zero Two to the point where she where she happily helps Zero Two wash her hair, plays with her in the water, and teases her about her relationship with Hiro.

Ichigo
In a mirror to Zorome's relationship to Hiro, she seems to have an inferiority complex to Ichigo, questioning her authority and openly talking behind her back. When Zorome challenged Hiro in Episode 2, she only agreed to go along with it after looking to Ichigo and pouring, and then claimed he didn't mind becoming Ichigo's partner, the reaction was enough to cut their connection.

Her envy over Ichigo being leader aside, in Episode 9 she calls Ichigo out on constantly letting her emotions overwhelm her every time things go even a little wrong, which is the opposite of how a leader needs to be. Even Ichigo can't argue with her. Miku was upset at her being inconsiderate of how Goro felt, as her partner.

Besides that, they seem to have a normal friendship and they can work together during missions.

Etymology
Miku's nickname may use some of the numeral's readings from her code: 390. mi from 3 (三, mi), and ku from 9 (九, ku).

Trivia

 * In one of the MATO comics, it appears that Miku and Zorome's matching necklaces are made out of Argentea, which is to remember their FRANXX and the memories they fromed together there by.
