Mizuki Konno is a high school student. She belongs to the the most powerful group in the class, which is led by Sakura Himezawa, so she can have a peaceful school life. One day, on the way to a school exchange event, a school bus driver becomes unconscious due to overwork. The bus goes off a cliff. Including Sakura Himezawa, a majority of Konno’s classmates die in the accident.

Raw emotions come to the fore in the face of this extreme situation. The five scatter instead of sticking together to survive.
