Izumi is managing a peaceful life at a magic school — until a pompous Nue named Shigure and a free-spirited Kamaitachi named Amagi crash into it. Meanwhile, his friend Yakumo is navigating a scheming kouhai named Ritsuka and a reliable, prince-like demon named Kazehaya. Two love triangles, one school where humans and supernatural beings coexist, and the story that forms where they intersect.
