An old school yakuza, Nagamasa Ryumatsu, ended up losing his life due to certain circumstances. But, when he awakened to a strange sort of scenery he had never seen before, he found that he had somehow changed into a beautiful girl!?

White swindlers (shirosagi) are those that cheat people to take their money, red swindlers (akasagi) are those that swindle the opposite sex, and black swindlers (kurosagi) are those that cheat the white and red swindlers. After his family is swindled by white swindlers, Kurosaki sets out to avenge them by becoming a black swindler.
