EPISODE 1: Alone and Lonesome!
Zero Two is seen on the carrier. She asks Nana where she can find an ocean, as she feels like swimming.

Zero Two is later spotted by Hiro skinny dipping in a lake near The Birdcage. She disappears, prompting Hiro to assume she is drowning and in need of rescue. Zero Two jumps out of the water with horns elongated and a live fish in her mouth. She spits out the fish and licks herself believing that she will taste "salty", to her disappointment.

Zero Two, in the nude, begins to converse with Hiro. She then tackles him into the water and licks his cheek, remarking that he tastes "dangerous" and she loves it. His "taste" coupled with the fact that he was not afraid of her horns (in fact, he loves them) prompts her to propose that he become her "Darling". Before Hiro can accept, Nana and Zero Two's "partner" arrive to retrieve her.

During the welcoming ceremony, a klaxosaur appears and attacks the new FranXX, damaging the garage. Zero Two piloting Strelizia- Stampede saves the Parasites, notably Goro and Ichigo, from a would-be particle beam. Strelizia and the klaxosaur battle causing catastrophic damage to the outer wall of The Plantation. Strelizia is overcome and is flung into a section of The Plantation, crashing where Hiro had been viewing the battle.

The lifeless body of Zero Two's partner, [Code: 081], drops out of the derelict Strelizia. Zero Two emerges from the wreckage bloodied and tells Hiro she'll have to pilot the Strelizia alone as "she always has". Hiro begins to reprimand her that if she pilots a FranXX in her current state she'll die. Zero Two claims she isn't afraid of death and if she doesn't do it countless more people will die from the klaxosaur attack. Hiro declares that he will ride with her. Zero Two asks if he's ready to die which Hiro states he doesn't know but he may very well be if he can't pilot a FranXX. Zero Two extends her hand to him mirroring their initial meeting at the lake. Hiro takes her and she pulls him into the cockpit declaring him her "Darling" and they kiss. The kiss reactivates the Strelizia and the Hiro-Zero Two pairing unlocks its "Iron Maiden" form to the amazement of Dr. FranXX and everyone else.

The new Iron Maiden Strelizia begins to overpower the klaxosaur and destroy it's core effectively killing the mechanical beast. In the aftermath, repairs are being done to the damage of the klaxosaur attack, Zero Two carrying an unconscious Hiro alight from the now deactivated Iron Maiden Strelizia. Zero Two gazes into the sunset and shoots Hiro a gleeful smile saying "I found you, my Darling!"

EPISODE 2: What it Means to Connect!
Zero Two is having breakfast at The Birdcage with the Parasites. She completely covers her meal in honey and proceeds to eat it with her bare hands to the disgust of all the Parasites except Hiro. She is approached by Zorome in an attempt to "hit on her"while putting down Hiro. She begins to wipe her honeyed hand on his uniform mortifying Zorome. Zero Two takes the pitcher of honey and starts sitting with Hiro and begins pouring honey all over his breakfast as well. She curls around him and calls him "darling" then proceeds to sit on his lap to feed him, much to the anguish of Ichigo so as to prevent her from finishing her meal.

Nana enters the room and informs them that Zero Two is on "standby" awaiting further other from HQ. She also commands to go back to her own table and not to mix with the Parasites. Zero Two antagonizes Nana stating that she merely wanted to have breakfast with her darling.

Later in the hangar, Zero Two is confronted by Ichigo. Ichigo thanks Zero Two for saving their lives but warns her to stay away from Hiro so as not to get his hope up then hurt him. Ichigo declares that she is not part of "their" squad. Zero Two approaches her and asks Ichigo what she "is" to her darling. Ichigo states that she is the leader of the squad. Zero Two begins to sniff her and lick her cheek astonishing Ichigo. Zero Two says she tastes "sweet" and that she likes her taste before gleefully leaving.

During the discussion for Hiro's parasite promotion, Zero Two volunteers to be his partner, he being he darling. Zero Two's proposal is met with harsh resistance by Ichigo, stating that she is not part of the squad and that if the test is merely to measure Hiro's aptitude it should work with her, having Zero Two participate would be unnecessary. Nana informs Zero Two that HQ hasn't authorized the use of the Strelizia so Hiro will have perform with one of his squadmates. Zero Two concedes stating that her injuries haven't completely healed yet. She allows Ichigo to have Hiro and go for it "this one time" and to make sure to take care of "her" darling.

After Ichigo's spectacular failure, Zero Two is shown flipping her hair in the wind and triumphantly eating her lollipop while leaving the training grounds.

EPISODE 3: Fighting Puppet!
Zero two is first shown waiting for Hiro to finish his solo training. After he finishes, he finds her asleep in an atrium. Once she wakes up, she takes him around the facility. However, due to Hiro's status he has limited access to certain areas, whereas Zero Two has an S-Class ID which implies unrestricted access. Thinking quickly, Zero Two takes Hiro's hand and they "waltz" through the doors, tricking the system.

Once gaining access, Zero Two leads Hiro to the Inner City of Plantation 13. While Hiro is awestruck by the view, Zero Two overlooks the city melancholically. Hiro shoots her a grateful look, and she asks him why he's staring at her. Hiro replies that he's trying to think of a name for her. Zero Two then jumps the rail and begins to walk out onto the ledge. She expresses her depressive view of the city, it's inhabitants and life. Zero Two then asks Hiro to run away with her offering to get him out of that place. Before Hiro can answer, Zero Two pretends to fall but actually somersaults back the the safety of the balcony. She lightly jokes that she was kidding.

Zero Two appears next when the underground mission against the Conrad-class klaxosaur went awry. While the team celebrates their apparent victory, Zero Two shows up in a dark corner remarking that it isn't over. All of a sudden a swarm of similar klaxosaurs and a giant version of the initial one begin to ambush the FranXXs. As the situation grows increasingly dire, Zero Two consistently prods Nana into letting her ride with Hiro in order to save them. Nana persistently denies her, till Hiro submits the Zero Two ride with Mitsuru, the only available "official" stamen, in order to save the squad. Zero Two is greatly disappointed in Hiro and gives him the silent treatment and she begrudgingly partners with Mitsuru.

The pair then race to rescue the squad. Initially, Mitsuru pilots the Sterlizia on par with Hiro that he proposes that Zero Two take him on as her "official partner". Zero Two puts him to the test and goes "All Out". Prompting Nana to initiate the retrieval of Strelizia and her stamen (Mitsuru). This results in a bloodied deactivated Strelizia. Zero Two emerges from the robot and gives Hiro a light wave and smile. Mitsuru does not emerge from the FranXX. He is shown to have passed out in the cockpit, bloodied and broken, on the brink of death.

EPISODE 4: Flap Flap!
In the aftermath of Mitsuru's near-death experience, Zero Two is told to return to the frontlines by Nana on Papa's orders and the Strelizia is grounded. Much to Zero Two's dismay.

Zero Two finds Hiro in the boy's bath and asks him to run away with her and leave his "weakling" comrades. Her mood dampens by Hiro's visible fear of her and asks him if he's like everyone else; if he thinks "she's a monster".

A giant centipede-like razor klaxosaur attacks the carrier meant to acquire Zero Two. Plantation 13 Parasites deployed FranXX to combat it, only to be ambushed by another klaxosaur. Zero Two and Hiro change into suits and rush into the situation room when Nana tells her that it won't help and the Strelizia is not authorized to "fly".

At this point, armed security personnel arrive to collect Zero Two and return her and the Strelizia to the front lines by any means necessary. Zero Two gives a long goodbye to Hiro remarking about how she "felt like things could work out too" and that she wanted to be with him. In lieu of a kiss, Zero Two pokes his forehead with her horns and departs with the soldiers.

While being escorted by the guards to the carrier, Hiro catches up to her, however unable to reach her due to restriction system. Hiro begins to shout out to her and apologize for his prior hesitation in the bath. Hiro explains that his fear was not of her inhumanity, but a lack of his own resolve. Hiro confesses that he doesn't care about riding the FranXX and that he just wants to with Zero Two and beg not to go. Zero Two pauses in the face of his confession. She then does a backflip, disarming one guard and using his rifle to crack the glass barrier above Hiro. She performs an aerial flip breaking through the glass reach Hiro. Now reunited, with a bashful Hiro, she coaxes him to reaffirm his confession asking him, "You wanna ride me, huh?". Hiro affirms that he does and Zero Two asks him to say it one more time, he then shouts it out for her.

Zero Two takes Hiro in her arms and they assume their waltzed pose in order to pass the restrictions and break through to the Strelizia. Once in the cockpit, Nana orders them over the comm to get out and that they do not have permission to launch. Zero Two declares she's going out with her darling and cuts Nana off in mid-sentence. Hiro pauses, due to his anxiety of failing to pilot a FranXX yet again. Zero Two reassures him that he can do it, later rephrasing it to "they" can do this. Now revitalised by Zero Two's encouragement, they pair-up and the Strelizia destroys the carries and takes to the skies en route to rescue the Parasites once again.

She insists on sitting beside Hiro at Futoshi's expense, thereby forcing Futoshi to sit at the girl's table by Kokoro's invitation. While Ichigo gives the morning prayer, Zero Two is hard at work slathering her entire breakfast (and Hiro's) with honey. She then begins feeding Hiro to the disgust of Goro and the jealousy of Zorome. Futoshi and Kokoro imitate them while Ichigo silently ponders into her teacup.

After breakfast, Hiro gives Zero Two a tour of The Birdcage and their life as parasites. Zero Two then divulges that she'll soon be living their too, her announcement causes displeasure among the Parasites, especially towards Ichigo who immediately confronts Nana about this development.

During the joint briefing between Plantations 13 and 26, Hachi informs them that Zero Two and the Strelizia will guard the main pipeline during the kissing. The plan is met with strong opposition by the leader of the Plantation 26 parasites. He recounts an operation from 2 years prior with Zero and his Parasites. He denounces Zero Two as "reckless and shows no concern for others", he even divulges that she is the reason his previous partner is dead. Zero Two utters "Weaklings die, Big Deal". The leader is about to attack Zero Two till Hiro intervenes and defends her honor, thus defusing the situation.

Later that night, Goro spots Ichigo and Zero Two sneaking out at midnight. Apparently Ichigo pulled Zero Two aside to ensure she stay in line for the next day's mission.

Ripping herself from Ichigo's grasp, Zero Two responds that "darling (Hiro) said that he wanted to ride with her. Ichigo continues to beg her not to put a heavy burden on Hiro. Zero Two questions Ichigo if she wants Hiro and reminds her that she tried to ride with him and that "they" didn't work. Ichigo exclaimed to leave her out of it, Zero Two confronts her that she should stay out of it. Ichigo asks if she's trying to "suck him dry", Zero Two declares "darling belongs to me". An agitated Ichigo warns her that Hiro could die. Zero Two brushes it off saying that he could, and if he did then he wouldn't have amounted to much. Angered and frustrated, Ichigo calls her heartless and inhuman. She then slaps Zero Two hard so hard it damages her headband, knocking it off. Zero Two becomes enraged, her eyes and horns start to glow a malevolent red. Red Zero Two then questions Ichigo on what it means to be "human". Frightened by the being before her, Ichigo runs back to the birdcage in tears and it starts to rain. Zero Two is calmed by the feeling of the rainfall.

The next morning, Hiro goes outside and approaches a soaked Zero Two by the lake. It is implied she spent the res of the night out in the rain. Zero Two tells him that everything smells nice after it rains. Zero Two reminisces of the time they first met. Hiro thanks for her that the reason he's still there is because of her and how she gave him the chance to pilot a FranXX. Zero Two unzips his uniform revealing a blue klaxosaur tumor (and the namesake of the episode). Zero Two asks him if it hurts and if he wants to walk away from being her partner.

Hiro [Code: 016]
Hiro is Zero Two's "darling". She states that they are the same and on multiple occasions declared Hiro the only one that's meant for her. While on board the carrier en route to Plantation 13, Zero Two first noticed Hiro trying to save a dying bird, she immediately exclaimed "Found you!". Zero Two took an interest in Hiro ever since they first met. Likewise, Hiro was immediately entranced by her horns (and his first look at a woman's fully naked body). She was impressed that he was not frightened by her horns (in fact he found them alluring). Zero Two and Hiro have a playful relationship; Zero Two would make these flirtatious advances towards Hiro, and he bashfully withdraws.

The first thing Hiro took note of was that her horns were "alluring"; Second, was she was his first-ever look at the naked female body. He was entranced and couldn't take her eyes of off her. After returning to his senses, Hiro inquires as to why she was bathing in the lake, to which Zero Two responds that she's disappointed that the "ocean" isn't salty. Hiro informs her that the lake isn't really an ocean. Zero Two retorts that it is the most ocean-like place she knows. She asks him if he wanted to swim since he was staring so hard. Hiro answers in the negative. After a brief pause, she accuses him of being a pervert noticing Hiro was in possession of her panties the whole time! Hiro explains that he found her clothes and thought she was drowning so he was gonna jump in to save her. Zero Two bursts into laughter, and thanks him for his would-be act of valour.

Given the circumstances of the situation, Hiro declares to pilot the FranXX with her. She swiftly questions him on whether he is ready to die, which Hiro affirms "that if he can't pilot a FranXX, he may very well be".

This time Hiro takes it without a second thought and Zero Two pulls him into the darkness of the Strelizia's cockpit. Zero Two announces that he is now her "darling" and they have their first kiss.

Later in the elevator Nama tell Zero Two not to mess with the parasite as she is "Too much for them to handle". During the discussion of Hiro's parasite promotion, Nana vetoes Zero Two's proposal informing her that HQ hasn't authorized the use of Strelizia.

Episode 3: Fighting Puppet!
While Nana is coordinating the seemingly successful mission in the super pipe, Zero Two suddenly appears in the room and begins to mock them that it's not over yet. Zero Two was right as a swarm of Conrad-class klaxosaurs emerge from the shadows of the underground and begin to overwhelm the FranXXs. As the situation becomes dire, Zero Two continues to jest Nana into letting her pilot the Strelizia with Hiro, but Nana does not bend. Zero Two and Nana begin to butt heads, before the tension escalates any further Mitsuru intervenes and volunteers to pilot the Strelizia, being the only available "official" stamen. Nana asks Zero Two whether she could ride with Mitsuru. Zero Two persists that she will only ride with Hiro. She then look over to Hiroto coax his affirmation, but Hiro tells Zero Two to ride with Mitsuru. He states that he'd rather have his teammates saved than be able to pilot a FranXX. Nana then coordinates the deployment of the Strelizia.

Later, Zero Two (Strelizia) decides to go on a rampage rather than comply with Nana's order to withdraw. Nana then deploys a team to "retrieve" the Strelizia and her Stamen. After the retrieval, Nana grimly looks at the sight of Zero Two as she exits Strelizia without her stamen.
