About Monster Musume: Harem Simulator

Monster Musume: Harem Simulator is a fan-made visual novel by BlackDahliaStudios, built in Ren'Py. You play Kimihito Kurusu, an average man who suddenly shares a home with monster girls. The game is based on the popular manga and anime and imagines a version where Smith allows monster marriage and breeding. It uses 2D CG and AI CG artwork, plays as a text-based adventure, and focuses on harem, monster girl, and romance themes.

Development is ongoing, and the current build is v0.3.0, released on September 18, 2025. The project is still in progress. It is available for Windows, Linux, and Mac, presented in English, and uncensored. The latest changelog entry adds Chapter 3, a Papi intro scene, and Tionishia dialogue and intimacy.
