For Hiro, failing a FranXX aptitude test has meant losing both confidence and the drive to become a pilot. He is one of the children bred to operate these giant machines in boy-girl pairs, defending humanity without knowing the world beyond their fortress cities, the Plantations. Outside, giant beasts called Klaxosaurs have brought humankind close to extinction, and FranXX are the only weapons known to work against them.
Absent from his class’s graduation ceremony, Hiro meets a girl with two horns at a forest lake. Her codename is Zero Two—the infamous pilot called the “Partner Killer.” A Klaxosaur attack interrupts their encounter. Zero Two fights it in her FranXX, but the damaged machine crashes near Hiro. With her partner dead, she offers him the other pilot’s place. Together, they defeat the creature with ease, giving Hiro a fresh opportunity to pilot alongside someone with a troubling reputation.
