Killed again, Mr. Detective.

Killed again, Mr. Detective. is a twelve-episode mystery series that aired in spring 2026, combining psychological and supernatural elements with a detective narrative that takes an unconventional turn. The story follows Sakuya Otsuki, a high-school detective trying to live up to his legendary father's reputation, as he repeatedly becomes a murder victim himself while investigating cases. His assistant Lilithea consistently discovers him dead, then helps piece together what actually happened, turning each death into another clue rather than a case-closing tragedy.

The series finished its run in 2026 with a complete twelve-episode season. What makes this show distinctive is its premise: rather than solving murders from the outside, Sakuya finds himself at the center of each crime, dying and recovering to continue his investigation with fresh perspective. The narrative structure treats his repeated deaths as part of the investigative process rather than punishment or obstacle, creating a darkly comedic hook within its mystery framework.

This title appeals to viewers who enjoy puzzle-box mysteries with an edge, psychological depth beneath genre conventions, and protagonists placed in genuinely difficult circumstances. The supernatural angle suggests deaths carry unusual weight and rules, while the high-school detective setting provides familiar grounding for the stranger elements that define each case.
