P-P-Possessed!?

Kitajima’s been accused of stealing the beauty of the school’s underwear. Coerced into apologizing, he agrees to meet the beauty named Kihouin and her friends at a karaoke joint. Kitajima didn’t do it and it was the girls who set about to humiliate him for fun. Too bad for Kihouin, because a friendly ghost decides to help out Kitajima in the best way possible.
