Akutou Ikka no Manamusume, Tenseisaki mo Otome Game no Gokudou Reijoudeshita.: Saijoukyuu Ranku no Akuyaku-sama, sono Dekiai wa Fuyoudesu! @COMIC

After her sudden death at the hands of an assassin, the former granddaughter of a yakuza boss reincarnates in an otome game as the heroine. The game is, of course, set in the time of early European mafia (but with magic), specifically a kingdom where the royal family is supported behind the scenes by five major gangsters!

A dangerous love game between a former yakuza heiress and her villain fiancé begins!
