Okusama wa Mahou Shoujo

A 26-year-old married woman secretly serves as a magical guardian named Agnes, protecting her town under a hidden identity. She encounters another magical girl, Cruje, who is officially designated as her successor by the magic realm. Agnes resists this transition, aware that Cruje’s mission involves erasing the town and all its human residents to make way for a new one. At the same time, Agnes deals with the increasing emotional distance from her husband, Tamotsu, and growing feelings for Tatsumi Kagura, a young man renting a room in her home. A key limitation is that any kiss from a human would permanently strip her of her magical abilities.
