Darling in the Franxx is set in a dystopian future where youth are artificially created and indoctrinated solely to defend the remnants of civilization. The story follows a squad of ten pilots, particularly focusing on the partnership between Hiro, a former prodigy, and Zero Two, a hybrid human and elite pilot who aspires to become entirely human. The series features symbolism relating to the mythological Jian , an imperfect bird with only one eye and wing and thus may only fly when paired with another. The animation began international distribution simultaneously upon its domestic release. The streaming service Crunchyroll internationally simulcast the series, with Aniplus Asia simulcasting the series to Southeast Asia.
Zero Two - Heroes Wiki - The ultimate good-guy resource
In a devastated future, humanity's only defense against the monstrous klaxosaurs are the children who pilot the robots known as Franxx. Failed Franxx pilot Hiro meets a mysterious horned girl just before his classmates' enlistment ceremony, and she doesn't care about his reputation. With no memory of piloting Strelizia, Hiro moves into the parasite dormitory. His classmates aren't thrilled to see him or Zero Two.
Zero Two has long pastel pink hair with a fringe and a pair of red horns on her head. Her eyes are cyan with pinkish-red eyeliner. Her eyes turn red without her headband. She has a slender and athletic figure; she is the tallest girl among the squad and about the same height as Hiro. Zero Two's full ensemble is composed of a white military cap with a matching overcoat and boots.
She is a human-klaxo sapien hybrid and a member of the APE Special Forces, primarily fighting on the front lines. As an elite Parasite with the codename "", also known as the "Partner Killer", Zero Two had always accepted solitude due to her horns and Klaxosaur blood. Despite having no regard for human life or her own and being accustomed to fighting solo, she took interest in Hiro and offered an opportunity to pilot with her, making him her new partner and "darling". Over time, Zero Two developed romantic feelings towards Hiro. However, her determination to become fully human, along with Hiro's apparent fear of her increasing feral characteristics resulted in the couple briefly drifting apart.
