A group of schoolmates from Kisaragi Academy perform a friendship charm called "Sachiko Ever After" for classmate Mayu Suzumoto, who is about to transfer to another school. Upon completing the charm, they are engulfed by an earthquake and transported to the cursed Heavenly Host Elementary School, separated from one another. Friends Naomi Nakashima and Seiko Shinohara reunite and search for an exit together, but find that all the windows and doors in the building are sealed. While they are resting in an infirmary, Seiko notices she has lost her paper charm slip and leaves Naomi to look for it. Naomi is then attacked by a ghost and narrowly escapes with her life before encountering a girl in a red dress. When Seiko returns, Naomi berates her for leaving and drives her away in anger. Naomi later searches for Seiko to apologize, only to find her hanged in a bathroom stall.
