Nagisa Shiratori, heir to a fading judo dojo left without human students, recruits animals from a nearby wildlife park as her sole pupils. To revive her family’s legacy, she reinvents herself as Japan’s top idol singer despite lacking musical skill, leveraging fame to attract disciples—a plan backfiring as her hectic stardom drives potential recruits away. Desperate, she adopts a male persona, Ootori Nagisa, and enrolls in a volatile Tokyo school. There, she defeats gang leader Tsunoda, earning his allegiance, and clashes with rival leader Nosaka Akira, sparking mutual romantic tension. Nosaka grows enamored with her idol persona, unaware of her true identity, while Nagisa conceals her feelings, their rivalry intertwining with unspoken attraction as they compete to recruit students.

Juggling idol duties and school life, Nagisa’s dual existence unravels when Nosaka discovers her secret during a violent skirmish. Choosing romance over rivalry, they vow to hide her identity, though meddling fathers and classmates threaten their fragile balance. Nagisa’s raw physical prowess and disdain for singing clash with societal pressures, yet her resolve to save the dojo remains unshaken.

Her struggles escalate amid surreal clashes with Momoko Prisilla, a reality-bending rival idol, and shadowy conspiracies targeting her fame. Adapting to escalating absurdity, Nagisa grapples with reconciling familial duty, personal ambition, and her feelings for Nosaka. By the story’s end, she sustains her dual roles, her partnership with Nosaka evolving into a strategic alliance that bridges their goals, even as chaos persists around her.
