The game follows Rinka, who, on her way to her first day of high school, is struck and killed at a crosswalk by a passing car while stopping to grab her shoe that falls off her foot. After death, she is greeted by Mr. Rabbit (a teacher with a rabbit mask) in the afterlife in front of NEVAEH Academy, a purgatory-esque setting for deceased students with strict rules including masked headgear for all faculty and students. A teacher at the school, Mr. Rabbit brings her to the academy's opening ceremony, which is attacked by the 'Bad Apples,' a group of students who oppose the strict authoritative nature that the schools runs on. Players are given the choice to side with bad apples or good apples (those who abide by the rules of the school administration, including the student prefects which enforce them), with each pathway involving unique branching paths and multiple endings which are dependent on choices made by the player during their playthrough.
