This is the beginning of a school and exorcism life for an exorcist four-eyes who can't see ghosts and a flashy guy who can see them but is terrified!

Sakaki entered Sanzu High School because of their high numbers of female students and his earnest desire to be popular. However, upon entering, he learned that it was a haunted school full of ghosts! He's been able to see ghosts since he was little and has experienced many scary situations, so he's now unwilling to go to the bathroom alone. One day when he's having stomach pains during makeup classes, he runs into his creepy classmate, Kataragi, and asks him to go the bathroom with him. Now he feels better... but when they arrive, an incredibly scary evil spirit is waiting for them in the bathroom!
