Indie mystery thriller visual novel Inquisitor Shepherd has released its free Steam demo on November 12, 2026, giving players their first opportunity to investigate its unsettling world. Developed by Korean two-person studio Narrowdeep, the game combines Lovecraftian horror, detective gameplay, and moral choices in a story about religious authority and accusations of heresy. The demo also includes Japanese voice acting, adding another layer to its narrative presentation.
The full version of Inquisitor Shepherd is scheduled to launch in 2027. Players take on the role of an inquisitor judge sent to investigate disturbing incidents in a remote village in Vucrium, a country governed by religious beliefs. As the investigation progresses, they must uncover hidden truths, identify deception, and decide whether the accused are guilty or innocent. These decisions directly influence the story’s direction and its multiple possible endings.
Inquisitor Shepherd Demo Introduces Its Heresy Investigation
The story takes place in Vucrium, where the player travels to a remote village following reports of increasingly disturbing heretical cases. What initially appears to be an investigation into suspicious villagers gradually develops into a mystery involving desperate lies and unsettling secrets.
The game features 15 unique characters, each with their own background, motivations, and secrets. Players must speak with suspects, gather information, and examine their accounts to understand what is happening in the village.
Exploration also plays an important role. Players can investigate specific locations, inspect objects, collect clues, and solve puzzles to advance the story.
One of the game’s central mechanics is Sin Powder, a special ability that enhances the inquisitor’s senses. It allows players to discover hidden information and uncover clues that might otherwise remain inaccessible. The ability can also help during difficult interrogations.
After collecting sufficient evidence, players must confront suspected heretics and determine whether their statements are truthful. However, not everyone accused of heresy is necessarily guilty. Players may also discover evidence that clears an innocent person’s name.

The final verdict, whether Guilty or Innocent, determines the accused character’s fate and can significantly change the narrative. With multiple outcomes, the decisions made throughout the investigation carry consequences beyond individual interrogations.
Narrowdeep is a two-person independent development studio whose partnership has worked on various projects since 2016. The developers describe their philosophy as creating games that explore a single concept and world in depth rather than pursuing a broader but shallower experience.
The studio also operates the secondary animation channel Olive Nara, which has approximately 60,000 subscribers.
Players can try the Inquisitor Shepherd demo through Steam, while the full game remains scheduled for 2027.
