Reiji and his sister Hisako are the children of the Kawaguchi group's leader, sworn enemies of the Seidoukai. Orphaned by the conflict between groups tearing the city apart, they are taken in by none other than Domoto, the head of the Seidoukai himself. Masatsugu, young heir to the Seidoukai, is immediately besotted with the siblings, cherishing and looking after them in the hopes of one day seeing Reiji and Hisako achieve their own bright futures, free from the stain of the criminal underworld. But his father holds less than noble intentions toward the two -- and there is no easy escape from the old hatreds and bad blood of the past.
