A man wakes up with no memory in a world that's already given up, and every frame forces you to ask whether living without purpose is even living at all. The show moves like someone thinking through their own mortality, not like it's in a hurry to entertain you. By the end you realize it wasn't asking you to solve who Casshern is, it was asking you to sit with the weight of existing when nothing around you believes you should.

A white-suited cyborg wakes in a dead world with no memory of how he got there. His name is Casshern, and everyone wants him dead. In this rust-colored wasteland where humanity and machines cling to survival after total annihilation, Casshern becomes a walking target. Creatures hunt him. Survivors curse his presence. Fragmented images flash through his mind, hinting at a past he can't quite grasp, a past that might explain the fear and rage directed at him wherever he goes. Casshern moves through this blighted landscape searching for answers about his own existence: who he is, what he is, and how he came to be here. Hidden somewhere in his mind lies a truth about his past that may prove terrible, one he has no idea is waiting for him.
