While still grappling with her death, she encounters a man named Koutarou Tatsumi, who reveals that he has resurrected her and six other zombie girls from various eras to economically revitalize Saga through an idol group. Taking on the role of a brusque manager, Koutarou starts scheduling events; the girls comply, eventually choosing to name their idol group Franchouchou.
