Killed. Sure enough, he is killed again. Oitsuki Sakuya's father is a legendary detective, but he himself is still a half-baked high school detective. Today, he accepts commissions as usual and takes on ordinary jobs such as extramarital affairs investigations or searching for cats with enthusiasm. However, no matter where he goes, he always gets inexplicably involved in murder cases, where the victim is actually himself! Every time Sakuya resurrects with his special constitution, there is always an excellent assistant, Lilithea, waiting for him to wake up with a knee pillow. "You've been killed again, Detective." "... It seems so." As a detective and also a victim, Sakuya always risks his life to solve one difficult case after another!
