At fifteen, Saki Uno balances school with her side‑hustle as one half of the notoriously unpopular idol duo Magical Twins. The duo"s popularity is minimal, but Saki remains determined. She juggles rehearsals and fan mail, hoping to someday rise above the crowd, while feeling invisible among the crowds of idols. She cherishes every moment with her best friend Sakuyo Mikage, dreaming of drawing closer to her childhood crush, Sakuyo"s brother Mohiro. Her calm routine shatters when a yakuza‑style thug attempts to break into her home. Coerced into letting him in, Saki discovers that her mother once battled as a demon‑fighting Magical Girl and that the rough outsider is actually a mascot named Kokoro‑chan seeking a successor. Confused and doubtful, Saki hesitates until Kokoro‑chan explains that Mohiro is being hunted by adorable, squirrel‑tailed demons.
Driven to protect him, Saki"s intense love unleashes her Love Power and a bold confession transforms her into a Magical Girl. Yet because her body cannot endure combat, the change morphs her into a muscular man dressed in an elegant gown. Now fully empowered, Saki must join forces with Sakuyo to shield the one she loves from the rampant fluffy demonic threats that plague her world.
