Yuki is a young bank employee, charismatic, but devoid of all morality. Garai is the guilt-ridden Christian priest who atones for Yuki's sins. They are accidental partners in theft, kidnapping, murder, and most frighteningly, in love.
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 (pronounced mu), used by American G.I.s. The Japanese and American governments are jointly covering up all knowledge of the chemical, leaving Yuki and Garai with no one to turn to. Driven by nothing but the desire to inflict evil upon the world, Yuki's salvation will only come from Garai's negotiation of the guilt-ridden torment of their forbidden love, and his responsibility to stop the vicious killer that the MW chemical has created.
