Why it matters
The pitch is a deduction game where the evidence itself is unreliable, since each suspect's cognitive abnormality can be transmitted to others and warp what witnesses perceive.
Key Facts
- Thermite Games and Smilegate released Byono Detective on November 5, 2026, for PC on Steam, Epic Games Store, and STOVE.
- The Steam standard edition costs 2,800 yen and the Deluxe Edition 5,035 yen, tax included.
- Indie studio PHOSEPO developed the game, set around 13 Byono-sha with different cognitive abnormalities.
- The Byono-sha can transmit their cognitive abnormalities to others, producing murder scenes that defy common sense.
- The scenario exceeds 500,000 characters and features full Japanese voice acting along with over 50 original BGM tracks.
The Steam standard edition costs 2,800 yen, the Deluxe Edition 5,035 yen, with a two-week launch sale of 10 percent and 15 percent off. Indie studio PHOSEPO developed the game, set around 13 Byono-sha whose cognitive abnormalities create murder tricks.
PHOSEPO's structure pairs a werewolf-style death game with a twist on testimony: the 13 Byono-sha can pass their own cognitive abnormalities to other people, so murder scenes are built from perceptions no ordinary logic can reconstruct. The cast includes a character who cannot lie because of obsessive-compulsive disorder, one who cannot recognize the left half of a scene and misses evidence, and one with prosopagnosia who cannot identify faces.
Deduction runs through a Debate Mode, where players decide within a time limit whether to accept a statement or present evidence against it. The game carries over 30 event CGs, more than 60 backgrounds, a scenario past 500,000 characters with full Japanese voice acting, and over 50 original BGM tracks.
