Murenase! Shiiton Gakuen

At Seton Academy, a school overrun by animals due to declining human numbers, Jin Mazama despises creatures of all kinds. As the only human boy in his class, he instantly falls for Hitomi Hino—the sole human girl. But his plans for a peaceful school life are disrupted when he gets unwillingly dragged into the “pack” of Lanka, a lonely wolf with no other members in her group.
