Created by BlendOver in Godot, Training the Demon presents an adult visual novel with 2DCG artwork and harem, management, and parody themes. You play a male protagonist in the Vortex World, a harsh setting where dangerous demons must be encountered and negotiated with. Recruiting friendlier demons and strengthening bonds matters because a mysterious energy makes close demon relationships key to survival.
Development is ongoing with v0.7.1 released August 22, 2026. It runs on Windows, Android, and Linux in English, Russian, Japanese, and Spanish, uncensored. The latest update adds Mermaid and Kikuri-Hime routes with four scenes each, a gallery, achievements shown as cards featuring Atlus character art, and playable demons Slime, Kodama, Lamia, Anahita, and Idun, none of which have bond content yet. It also introduces skill selection during fusion, reverse fusion from a result, and learning one chosen skill from a demon that has learned all of its skills.
