Fifteen years ago they witnessed and survived the chemical decimation of a seaside village rumored to have been the hiding place of an experimental psychotic drug, called MW, used by American soldiers. The Japanese and American governments are jointly covering up all knowledge of the drug, leaving Yuki and Garai with no one to turn to. Driven by nothing but his desire to inflict evil upon the world, Yuki's salvation can only come from Garai's negotiation of the guilt-ridden torment of their forbidden love, and his responsibility to stop the vicious killer the MW chemical created.

This is Osamu Tezuka's controversial testament to the art of character, one that redefines both sin and salvation.
