DARLING in the FRANXX

Promising student Hiro fails to qualify as a Franxx pilot, but gets a second chance when he meets Zero Two, a girl with red horns who loses her Franxx copilot in a monster attack.

Hiro can't remember how he and Zero Two win their first battle together, which casts doubts on his qualifications as a pilot. The instructors order him to prove himself in a mock battle without Zero Two as his copilot.

Without the confidence of his superiors, Hiro is sidelined as his fellow pilots struggle to defend against the monsters. Zero Two heads out with someone else, pilot Mitsuru.

Doubt surrounds Strelizia's combat readiness after Mitsuru is badly wounded, but the leaders must send Strelizia back into battle when another monster appears. This time, Hiro pleads with Zero Two to partner with him again.

When the time arrives for Plantations 13 and 26 to begin kissing, the squad prepare for the huge battle this will cause. Everyone must adjust to Hiro being Zero Two's new partner.

A greater threat than ever faced before emerges in front of the Franxx squads, and Hiro accompanies Zero Two on a mission that could be their last.
