The premise hooks you instantly: Sakuya dies in every case, then wakes up next to Lilithea to solve it anyway. Each death isn't a reset button or a cheap trick, it's the actual investigation, the thing that forces him to see what he missed the first time. The show treats dying repeatedly as a detective method, not a gimmick, which means every corpse in the room might as well be his own.

Sakuya Otsuki is the high-school son of a legendary detective, and he works alongside his assistant, Lilithea. He prefers safe jobs like cheating spouses and missing cats to the risky exploits his father was known for. There's just one problem: wherever a case takes him, Sakuya tends to become the murder victim. A job aboard a luxury cruise ship turns up a dead body, and before long he is killed yet again. But death isn't the end here. Every time he dies, Sakuya revives some time later with Lilithea at his side, so he keeps digging into the crime as both detective and victim. Expect a supernatural mystery with a psychological edge.
