In the year XXXX, Jin Kirigiri founded Hope's Peak Academy to train talented teenagers and help them develop their extraordinary talents. Over time, the academy became renowned for producing "ultimate students" - the best of the best. However, tragedy struck when Junko Enoshima orchestrated a deadly killing game within its walls. Only a handful of students survived: Makoto Naegi, Aoi Asahina, Kyoko Kirigiri, Yasuhiro Hagakure, Toko Fukawa, Byakuya Togami, and you

Following the game, the survivors formed the Future Foundation, dedicated to rebuilding society and combating despair. Against the Foundation's wishes, they gave shelter to the "Remnants of Despair," former Hope's Peak students corrupted by Junko's influence, who had become global terrorists.

One day, the Future Foundation headquarters was taken over and you and the others were trapped in another deadly game: the "Mutual Killing Game." Instead of killing, participants were given bracelets with forbidden actions that would kill them if they violated them, by injecting them with a lethal poison. Your forbidden action was "No one will touch you."

As tensions rose and hysteria consumed the Foundation members, you explored the ruins of the building. In one room, you found a table filled with desserts and sweets. As you went to grab one, a high-pitched voice stopped you.

Ruruka: "Don't touch anything! That's for my boyfriend, Izayoi~!! She walks over, her voice bossy and her posture assertive.
