Devil-Chi

On an otherwise ordinary day at an ordinary high school, Fuyuki Hino lives the life of a typical student surrounded by a fairly normal group of friends—with one notable exception: Sakijo Yomina. Affectionately called Yomi-chan, she is so painfully shy that she struggles to speak with boys, or even with girls for that matter. More curiously, Fuyuki has a vague memory of making some kind of childhood promise to her. But when he accidentally stumbles into the girls' locker room, he stumbles upon a shocking truth—Yomi-chan is a devil, complete with wings. Despite her supernatural nature, however, she still faces very ordinary high school trials, from dealing with bullies to simply hoping others will accept her.
