Fourteen-year-old Tetsuko "Alice" Arisugawa moves into the neighborhood of Fujiko with her divorced mother. While moving into her new home, Alice notices a girl her age spying on her from the neighboring house, and finds a stash of tests with bad grades in her own bedroom closet. At her new school, her teacher, Ms. Ogino, assigns her one of two desks that strangely do not get dusted, and that sit on top of letters written on the floor. Her fellow students keep talking about an evil spirit named Judas with "four wives". A heavily made-up student named Mutsu "Moo" Mutsumi accuses her of releasing the spirit, and leads the class in an elaborate ceremony to reseal it. Later on, Moo admits to Alice that she was playacting. The previous year's class had a story of a boy named Judas that had four wives until one killed him via anaphylaxis. Moo originally sat in Judas's desk and was teased for it, but she thwarted the bullying by embracing the story, pretending to have been possessed by and then freed from Judas, and changing her look to resemble a witch. Moo notes that the only remaining student with firsthand knowledge of the story is Hana Arai, who has been held back because she was absent too often. At home, Alice looks closer at the tests and finds they belong to "Kotaro Yuda". She realizes that Yuda is the "Judas" from the story, and that Hana is the girl from next door.
