On September 11, 2026, the developer posted a formal announcement confirming that a scenario update is nearly finished and scheduled for release between October and November 2026. This update includes 3 new floors based on the original source material, a new "Further Achievements" quest, and new cards, skills, and anomalies.

About this game

"Arai-san Mansion Exploration Game: Incarnation" is a command-based text adventure game inspired by the "Kemono Friends" fan-art series by Abubu-shi.

As an agent of a specialized investigation organization, you must step into the "Arai-san Mansion," a place swarming with paranormal phenomena. Your mission is simple but dire: explore its many floors using the elevator and ensure that these anomalies never leak into the outside world.

Game Features

  • Infinite Floors: The combinations of elevator buttons lead to an astronomical number of destinations. From floors shrouded in absolute silence and floors inhabited by Friends, to floors where death is certain in a single step... Knowing when to retreat is just as important as the courage to explore.

  • Strategic Card-Based Exploration: The keys to your survival are your "Skill" and the "Action" and "Ally" cards you collect. Your choice of skills and cards will branch the narrative and open new paths.

  • Diverse Mechanics: Centered around tense card battles, the game challenges you to uncover the truth through detailed text and overcome eerie gimmicks. Use every tool at your disposal to solve the mysteries of the mansion.

Game Flow

Your journey begins at the Entrance Floor, which serves as your base. Prepare yourself at the Market before heading into the floors via the elevator. There are two types of floors:

  • Special Floors: These contain unique events that advance the main story.

  • General Floors: These are spaces for training, earning money, and encountering paranormal entities.

Controls

  • Mouse: Select options, choose cards, and navigate menus.

  • Mouse Wheel: Scrolls the message when it overflows the message window.

  • Arrow Keys: Move between options.

  • F1 Key: Hide text window (useful for viewing background art or characters).
