Darling in the Franxx (ダーリン・イン・ザ・フランキス) is a 2018 Japanese science fiction anime television series co-produced by Trigger and A-1 Pictures that premiered on January 13, 2018. The series takes place in a post-apocalyptic future where humanity has been driven to endangerment by giant beasts known as klaxosaurs. The remainder of humanity soon establishes a military city known as Plantation, where children are bred to be partnered in boy-girl pairs called Parasites and pilot giant mecha known as Franxx. One of these children, Hiro, is initially viewed as a prodigy, but after failing one of his tests, his resulting emotional stress leaves him unable to pilot a Franxx, making him lose any desire he had in life. While skipping out on his class’s graduation ceremony, Hiro encounters Zero Two, an infamous Franxx pilot who is a member of a race of humans with klaxosaur blood, leaving her with red horns on her head. After Zero Two’s partner is killed in a klaxosaur attack, she convinces Hiro to become her new partner, or “darling” as she puts it.
