The mafia boss of the Iwashi family is a high school girl named Konomi Minoko. But don’t let her appearance fool you; she has done and seen things normal citizens can’t even imagine. Under her control are two assassins who have gained legendary status for their deadliness and ability to get any job done. Ishikawa Rushia, codenamed Baret, uses a modified handgun that uses a custom-made hollow point bullet that explodes the target from the inside. Shirato Marin, codenamed Francesca, uses an original weapon that is a mix between a throwing ax and battle-ax. Both of them are Minoko’s high school classmates and seem like normal teenagers but are two of the most feared killers in the mob world who handle missions often involving other assassins and underground groups.
