Smilegate's global gaming platform Stove will showcase its co-published new title, 'Psycho-Sleuth', at Tokyo Game Show 2026, which runs from August 17 to 21 at Makuhari Messe in Chiba Prefecture, Japan.

'Psycho-Sleuth' is a psychological mystery visual novel developed by PHOSEPO and co-published by Thermite Games and Smilegate Stove. Visitors to the Smilegate Stove booth at this year's Tokyo Game Show can get their hands on a playable demo.

'Psycho-Sleuth' follows the harrowing tale of 13 individuals suffering from cognitive disorders trapped in a deadly death game. Each character's unique 'pathology' serves as the core element of an inventive deduction system. The culprit in the game uses this very ability to warp the player's vision and controls in real-time, throwing wrenches into the investigation. Players must enter 'Debate Mode' to pick apart contradictions piece by piece, hunting down the mastermind hiding behind the infected cast's warped perception. The ultimate goal is to unmask the killer amidst chaos where lies spread like a virus.

The game boasts a massive narrative spanning over 500,000 characters, complete with full voice acting for key scenes. Immersion is dialed up further with around 40 CG illustrations, dozens of 3D backgrounds, Live2D animations, and over 50 original background tracks. Through this publishing partnership, Stove plans to support Korean localization and marketing campaigns so that local players in South Korea can naturally experience the unique narrative and deep emotional resonance of 'Psycho-Sleuth'.

'Psycho-Sleuth' is scheduled to land on PC platforms on November 5, available via Stove and Steam. The title will support Korean, English, Japanese, and Chinese.

Meanwhile, the Smilegate Store booth at Tokyo Game Show 2026 will also feature 'Detained: Too Good for School', a punchy 2D action RPG starring delinquent high school girls.
