Ganta is the only survivor after a mysterious man in red slaughters a classroom full of teenagers. He's framed for the carnage, sentenced to die, and locked away in the most twisted prison ever built: Deadman Wonderland. And then it gets worse.
Ganta, battered in battle and weakened by the poison coursing through his body, tries to use the last of his strength to take out Genkaku - but Shiro might be his only hope.
