20-year-old virgin Nishizuru Yatsuki has always considered himself a fairly normal guy-he’s a high school graduate, works a part-time job, and hangs out at a maid cafe. He does have one very special ability- he can see yokai spirits! Usually he copes with these ghostly visions by ignoring them-but everything changes when he meets a beautiful young woman named Rokka. Now Yatsuki’s normal days have taken a notably abnormal turn, as he finds himself the sole defender of a growing harem of supernatural-and super sexy-yokai girls!
