A 26-year-old wife keeping a secret: she's the magical girl protecting her whole town, and nobody knows. When the realm sends her replacement with orders to wipe everything clean and start over, Agnes has to choose between obedience and the life she actually built. The show strips away the transformation sequences and flashy combat, what's left is two women negotiating power, legacy, and whether saving a place means you get to keep it.
Ureshiko leads a double life as a devoted housewife by day and magical girl guardian by night. For years, she's protected her town under the alias Agnes, keeping her secret identity from everyone around her, including her husband Tamotsu. Her carefully balanced world fractures when Sayaka arrives as the officially appointed successor, tasked with destroying the entire town and rebuilding it from scratch. Caught between duty and survival, Ureshiko refuses to step aside. The situation grows messier when Tatsumi, a charming young man, moves in as their tenant. As emotional distance grows between her and Tamotsu, Ureshiko finds herself drawn to Tatsumi in ways that threaten everything. There's a catch: if she ever kisses an ordinary human, her magical powers vanish permanently, leaving the town defenseless. Ureshiko must navigate competing loyalties, unexpected attraction, and the weight of her responsibility. She faces an impossible choice between her secret identity and her heart, all while preventing her town's annihilation.
