School of Pandemonium(妖怪!百鬼夜高等学校)

When the clock in the school building strikes midnight, the campus will become "a school for yokais" that cannot be seen with human eyes. Tanaka Kazuo is a human high school student with no friends who is bullied by his classmates. He feels miserable and lonely, believing that he doesn't belongs anywhere. However eveything changes when he discovers the existence of the yokai realm. Hoping to make some friends and to start a new life, he enrolls himself in the school and lies saying that he is a very rare mixed-race yokai called "Tanaka Ichiotoko", despiste the fact that he looks like an ordinary human being. Tanaka's new supernatural classmates are full of surprises, and can't help but suspect of his true nature.
