Something is deeply wrong with my class. Following the death of Amane, our beautiful and seemingly perfect classmate, everyone has gathered to hold a funeral in her honor. Although fear permeates the room, no one speaks openly, and I am certain they are concealing something. Before she died, Amane made a disturbing remark that now haunts us all. Could there be traitors among us? We have decided to hold a class meeting, and no one will be allowed to leave until we uncover the truth behind what happened.
