Mata Korosarete Shimatta no desu ne, Tantei-sama

Mata Korosarete Shimatta no desu ne, Tantei-sama follows the brilliant but perpetually unfortunate high-school detective, Sakuya Otsuki. Aspiring to live up to his father's legendary reputation, Sakuya investigates intricate mysteries with his steadfast assistant, Lilithea.

This anime presents a unique twist on the detective genre: Sakuya has a peculiar tendency to become personally entangled in every case—as the murder victim. Each time he is killed, he awakens with Lilithea at his side, ready to help him retrace his steps and solve the crime from beyond the grave. The narrative cleverly blends suspense, deduction, and a touch of the supernatural as this duo unravels conspiracies, starting with a high-stakes infiltration of a luxury cruise ship.

The core of the anime explores themes of determination, partnership, and the cyclical nature of solving puzzles where the detective himself is the ultimate clue.
