Is survival in the cards?

"The Empire of Japan, 1989... Awoken in a decaying old bunker, sixteen elite Absolute Students are trapped in a kill-or-be-killed Apathy Experiment. Will they band together to uncover secrets of this anemoic alternate past, or lose their humanity and lives in the present?"

With a visual style inspired by Rumiko Takahashi’s Urusei Yatsura and '80s anime alongside classic Japanese mystery-adventure games like Danganronpa and Ace Attorney, Kumitantei™ thrusts you into a suspenseful character-driven killing game narrative where your deckbuilding and detective skills are the only keys to surviving. It's a creepy-cute love letter to decades of ADVs that wears its many inspirations on its sleeve: perfect for fans of visual novels, detective games, and deckbuilders with deep narratives.
