One of the girls in the first year class is jealous of the other girls in her class. She's also a member of the super-natural studies club, so she's the president of the club. The other girls are jealous of her, too, because she has a crush on a student named yamada. The girls decide that they're going to have a "witch power" , which basically means they'll be able to "switch bodies" with the girl. They decide to do this because they hate her, and they want to "catch urara shibutani off-guard" and kiss her.
