The game turns cognitive disorders into the deduction system itself, so the murder scene and the testimony both change depending on who is perceiving them, and the player has to doubt their own reading of the case.

Thermite Games announced on September 15 that Byounou Tantei, a suspense mystery adventure developed by indie studio PHOSEPO, will launch for PC via Steam and STOVE on November 5, 2026.

Thermite Games dated the release on September 15. The game runs on PC through Steam and STOVE.
The premise is a death game run by a cult called Ri. Thirteen characters carry rare cognitive disorders, and those disorders spread to the people around them, producing crime scenes that ordinary reasoning cannot untangle. Prosopagnosia, spatial neglect, and compulsive truth-telling all appear among the cast. Deduction happens in Ronben Mode, where clues are thrown at another character's testimony. The script runs past 500,000 characters with Japanese voice acting for major scenes.
