Otome*Domain The Animation

After his grandmother passes away, Minato is left completely alone with no family and nowhere to live. Then a well-dressed stranger named Kazari shows up at the funeral and offers him a deal: enrollment at a prestigious school and a place to stay. Sounds great, until he finds out the school is an all-girls academy — and the only way he gets in is by disguising himself as one of the students. He takes the deal anyway, because what else is he going to do. Once he moves into Dorm II, he quickly realizes his housemates are a lot to handle. Yuzu runs the newspaper club and has the stubborn confidence to match, and then there's Hinata, who insists on being called 'Zarathustra, General of the East' and lives inside her own fantasy world. Minato somehow ends up as the unofficial caretaker of the whole dorm, cooking and cleaning while trying not to blow his cover. It's a single OVA episode based on a visual novel, so don't go in expecting a full arc — it's a quick, light-hearted slice of the setup. The humor comes from Minato being the only grounded person surrounded by chaos, which works well if you liked the cross-dressing comedies in Otome wa Boku ni Koishiteru or the awkward social dynamics of Maria Holic. If Kämpfer's gender-swap premise interested you but you wanted something with less action and more domestic absurdity, this scratches that itch.
