Sleuth out the reincarnators. Retrieve their jeweled eyes. Stop this world's destruction. That's Ailn's reluctant mission -- except he's not really Ailn. He's an impostor: a detective from another world who can't even remember his own name.

"You took my memories, and expect me to do you a favor?"

"Taking them away was my favor, Mr. Detective. Some endings are just too bitter."

Summoned by a young god with a terrible habit of hiding crucial details, the detective must unmask other reincarnators -- all while wearing a mask of his own. Now he's 'Ailn eum-Creid,' the noble son of a family that's protected the empire for countless generations.

But the young god neglected to mention just a few things: the original Ailn had a trash reputation, he was just killed, and the prime suspect is his sister, the duchy's beloved future Saintess.

First things first. Time to solve his own murder.
