Mata Korosarete Shimatta no desu ne, Tantei sama

In Mata Korosarete Shimatta no desu ne, Tantei-sama, Sakuya Otsuki is determined to step out from the shadow of his legendary detective father and prove himself as a high-school sleuth, with his assistant Lilithea always at his side. He is sharp, stubborn, and eager to solve any mystery that comes his way, but he is also cursed with a bizarre misfortune: wherever he goes, he tends to become the victim, and every investigation threatens to end in his own death. That curse reaches a new level when Sakuya is ordered to infiltrate a luxury cruise ship. He is killed once again, only to open his eyes and find Lilithea waiting beside him as if nothing has changed, ready to guide him back into the case. As the pair continue their investigation, each death and return pushes them deeper into the truth behind the killings. What begins as a dangerous assignment becomes a tense partnership built on deduction, trust, and relentless persistence, with the mystery tightening around them on the ship’s isolated decks.
