Deadman Wonderland

A massive earthquake ravaged Japan's mainland and destroyed most of Tokyo, sinking three-quarters of it into the ocean.

Ten years later, the story starts with Igarashi Ganta, a seemingly ordinary, unassuming middle school student attending Nagano Prefecture's middle school.

An escapee, a survivor of the great earthquake, Ganta has no memories of the tragedy and has lived a simple, normal life.

This all changes one day when a strange man covered in blood and crimson armour appears, floating, out of his classroom windows.

Smirking madly, this Red Man massacres Ganta's entire class and, instead of killing him, embeds a red crystal shard in his chest.

Within days of the massacre, Ganta is declared the sole suspect and, following a suspiciously quick trial, is sentenced to death and imprisoned in Deadman Wonderland, a massive theme-park-like prison.
