義母の愛はママならないっ！

Shotaro Kuzukake is a high-schooler whose only remaining family member disappears on a trip, leaving him to fend for himself. The rescue arrives as a squad of self-declared stepmothers who take over everything, from the housework to the rest of his daily life. Each one is stranger than the last, and Shotaro ends up at the center of an unpredictable harem romantic comedy run entirely by mothers.
