Plot

Touta, Kuroumaru, and Karin are on a mission protecting the poor residents of the slums when they come under fierce attack by powerful enemies who seem to specialize in hunting down and killing immortals. Touta and Kuroumaru take a nasty beatdown, and in a moment of desperation, Touta finds a new power that may be great or terrible—or both!
