Maki Kisaragi wants to be an ordinary high school student, unfortunately, she is the heir to the Kisaragi Group (a mafia/yakuza related company).
One day, shes sees some men from the Kisaragi Group being beaten, and when she hears the "Kisaragi Group' being loudly taunted, she turns into a completely different personality, a fighting-yakuza-badass type that can block bullets and such.... So, she beats all the bad guys up, and suddenly turns back into a normal girl, with no memories of what she had just done...
