The Premise of the Immortal Sleuth

At the heart of Killed Again, Mr. Detective? lies Sakuya Outsuki, an ordinary high schooler burdened with an extraordinary ability: he possesses the power of resurrection, returning to life after every death. Utilizing this unique, almost immortal trait, Sakuya operates as a detective, solving cases that often blur the line between the mundane and the metaphysical. He is supported in his investigations by his capable assistant, Lilithea.

The plot promises intricate twists and high stakes, beginning when Sakuya embarks on an investigation into a gripping murder aboard a cruise ship destined for Singapore. This initial case soon becomes deeply entangled with a larger, more mysterious saga involving his father and a historical hijacking incident. The narrative masterfully weaves together elements of profound supernatural suspense with classic, detailed detective methodology, making it a must-watch for aficionados of mystery and high-stakes drama.

Before its upcoming anime premiere, the story successfully transitioned into the manga medium. Illustrated by Inaba, the manga ran from July 2022 until its conclusion in March 2024, collected across two volumes. This manga adaptation was made accessible to English-speaking audiences through Yen Press. This forthcoming anime adaptation serves not only as a validation for the devoted existing readership but also as the perfect entry point for newcomers eager to dive into a compelling tale of an immortal sleuth navigating danger and secrets.
