"Please find the person who killed me—Detective." July, ■th. On a summer day when the mysterious and beautiful girl, Momiji Reido, transferred to our school, a classmate was murdered. It was a locked-room murder. “Let’s solve the case together, Amami-kun.” “You sound just like a famous detective from a mystery novel.” I, Haruma Amami, a member of the nearly-disbanded Literature Club, was somehow asked by the transfer student to investigate the case. And then, Reido was killed—or so it should have been. Inside the ultimate locked room, one that no one could possibly solve. "Please find the person who killed me—Detective." An immortal detective and his “ordinary” partner. A school mystery that takes on an impossible murder—begins now!
