Detective who dies and revives is unique twist—Sakuya coming back to life every time he's killed removes death as consequence but creates new narrative possibilities. Rie Kugimiya joining the cast is exciting; her distinctive voice adds star power to the mystery ensemble. Dying every case creates interesting stakes—knowing Sakuya will revive doesn't diminish tension when investigating dangerous situations. Four new characters expand the mystery ensemble; adding Katsuyuki Konishi, Yoshino Aoyama, Rie Kugimiya, and Yuki Takada suggests complex character dynamics.

A brand-new teaser visual and four additional cast members were revealed for the Kill Again, Mr. Detective? anime before its planned April 2026 broadcast today.

About the Series

Yen Press publishes an official English version of Inaba's manga adaptation.

The Story

Yen Press describes the story:

Sakuya Outsuki is the son of a legendary detective, striving to follow in his father's footsteps with the help of his assistant, Lilithea. This isn't your average high-school sleuth, though—because he comes back to life every time he's killed!

Being a little too familiar with death and always awakening to Lilithea by his side, Sakuya's happy to take on low-risk cases. Surely investigating a movie producer's affair on a luxury cruise ship won't pose any real threat! But when the duo ends up entangled in a larger and bloodier situation, Sakuya will have to get to the bottom of the mystery…and die trying!
