Terada Youhei is your average high school student whose only talent is his ability to see ghosts. One night he meets "Rooftop Rinko-san", a ghost who resides on the rooftop of his school. Because she was unable to make any friends during her life, does that make her the type of ghost who won't let anyone who meets her leave the rooftop...? It's the story of a hilarious friendship between man and incompetent ghost girl!

Onizuka is an Oni and her childhood friend Sawarida is a human who likes to touch weird stuff. She might be in love with him, but he is too dense for love or is it the other way around?
