Saki Uno is an average 15-year-old girl with a side hustle as a member of the exceptionally unpopular idol duo Magical Twins. Despite this, she absolutely loves the time she spends with her best friend Sakuyo Mikage as she strives to become closer with her childhood crush, Sakuyo's brother Mohiro. Her peaceful life, however, unravels when she finds a yakuza-looking thug trying to enter her house. Forced to invite him inside, Saki learns that her mother used to be a demon fighting Magical Girl, and that her brutish guest is actually a mascot named Kokoro-chan looking to recruit a replacement. Dumbfounded and skeptical, Saki is hesitant accept the request until Kokoro-chan reveals that Mohiro is a target of some cute, squirrel-tailed demons.
Rushing to his side, Saki's overwhelming desire to save Mohiro activates her Love Power, and a daring confession awakens her as a Magical Girl. However, because her body is not suitable for combat, Saki's transformation turns her into a muscle-bound man clad in a pretty dress. Now, as a fully-fledged Magical Girl, Saki must team up with Sakuyo to protect the love of her life from the fluffy, demonic menaces that run rampant in her world.
