Synopsis: DARLING in the FRANXX

In a far-off era, Klaxosaurs - colossal creatures - have brought humanity to the brink of extinction. People have sought refuge in Plantations, colossal fortress cities. Within these cities, children are reared to drive giant FranXX mechas - the sole means of combating the Klaxosaurs - in boy-girl pairs. These kids were bred exclusively to drive FranXX and, as a result, know nothing about the world outside the Plantations, using their skills solely to protect humanity. After failing a test to drive a FranXX, Hiro loses faith in himself and skips his graduation ceremony, retreating to a forest lake. There, he comes across a girl with two horns sticking out of her head; the enigmatic Zero Two, a FranXX pilot renowned as the infamous "Partner Killer." The Plantation is suddenly rocked by a Klaxosaur attack, interrupting their meeting. While fighting, Zero Two's FranXX is severely damaged, crashing close to where Hiro is. After finding her co-pilot dead, Zero Two asks Hiro to help her pilot the mecha, and they quickly conquer the Klaxosaur. Hiro is given a chance to redeem himself with a new partner, but only at what price?
