Maybe it's more like a scripted Werewolf than a scripted killing?
I don't know what to count, but it's just a group of detectives playing a game of "killing" each other.
And a trouble-making organization surging under the game.
Inspired by the book "No Survival" and Conan's Dusk Annex.
Purpose: Whether it's exploring the truth or upholding justice, pursue what you want to pursue and become the person you want to be.
