In a distant future where cyborgs and humans struggle to survive after a devastating war that destroyed the world, a white‑suit‑wearing figure awakens with no memory of his past. His name is Casshern. The bleak, dark dystopia he inhabits is hostile, and every living being seems to despise his existence. Dark forces from his past hunt him, and flashes of forgotten memories haunt him. He must survive, discover who or what he truly is, and uncover how he ended up in this ruined world. In the process, he may learn a horrible truth buried deep within his mind. Casshern Sins is intended as a reboot of the Casshern franchise.
