The plot of the Corpse Party series concerns a group of Japanese high school students who, after celebrating their school's culture festival, are telling ghost stories when a sudden earthquake transports them to a dilapidated schoolhouse in an alternate dimension that is haunted by the ghosts of people who have been trapped there. The main playable character is Satoshi Mochida, a kindhearted high school student who is teased by his classmates for his cowardly nature. Three of the other characters are students from Satoshi's class: Naomi Nakashima, Satoshi's childhood friend; Yoshiki Kishinuma, an intimidating yet good-natured student; and Ayumi Shinozaki, the class representative. Rounding out the group is Yuka Mochida, Satoshi's younger sister. The game's antagonist is the red ghost of a teenage girl who seeks vengeance for her wrongful death.
