Enjoy fun encounters with monster girls.
About
This is modern-day Japan, where humans coexist with demi-humans, commonly known as monster girls. In this society, monster girls and humans live their lives side by side.
This is a multi-species spa resort, a facility designed to be enjoyed by everyone from giant demi-humans to those nearly human in appearance, and of course, humans themselves.
Here, you can meet, have fun, and play with all kinds of monster girls!
-
The resort's facilities and equipment are state-of-the-art, ensuring all species can use them without inconvenience, and are built to be durable enough to withstand even the rowdiest giant demi-humans.
-
Swimsuits are mandatory inside the resort, but the rules are a bit lax as long as the bare minimum is covered.
-
Fighting and acts of violence are strictly prohibited within the resort.
