About Monster Girls Onsen

Monster Girls Onsen is an 18+ anime visual novel with light management elements, set at a mystical Japanese hot spring you unexpectedly inherit. By day, you run the onsen, serve guests and expand its facilities. By night, you meet four monster girl spirits: the regal sun goddess Amako-sama, the shy ghost Senako, the icy beauty Yukino and the playful fox Hina.

Run the onsen

Manage and upgrade your traditional Japanese onsen as you work to establish yourself as its rightful master. You must earn the spirits’ trust and satisfy their desires.

Art and storytelling

The game combines cozy management with erotic storytelling, using 2D anime-style art with a classical Japanese aesthetic.
