Immoral-Bathhouse is a Unity adult dating sim and management game by Butter Cat Studio, rendered in animated 2D CG art. You play as Ryouji, a man whose mysterious illness, debt from his father, and need for intimate relief push him to take over Tenryuu Bathhouse. Earning money lets him improve facilities, add services, and attract more customers, while his symptoms can force urgent action. As owner, he works to draw seven distinct heroines into the bathhouse, and repeated contact can deepen both emotional and physical ties. Players may also explore mountain areas to gather herbs, craft medicines, and sell them for profit. Each day is split into four periods for visiting locations, talking with characters, gaining information, and raising favorability. Ignoring his condition can lead to collapse, hospital costs, or death.
The current build is v0.0.54, dated May 14, 2026, and development is ongoing. It runs on Windows with English, Japanese, Chinese, and Korean language support, and is uncensored. The newest patch replaced redrawn ending artwork for Kasumi and revised some text.
Developer's description
You play as Ryouji, a man who, due to a series of unfortunate events, has contracted a mysterious illness.
After being drugged by his own father and burdened with his debts,
Rouji discovers that his condition requires regular release through contact with female hormones to avoid worsening symptoms.
To manage his finances and treat his condition, he takes over the management of the Tenryuu Bathhouse.
By earning income through the bathhouse, he upgrades its interior, expands services, and raises its reputation to attract a wider range of customers.
However, when Ryouji’s libido spikes due to his illness, he must take action.
Using his role as the bathhouse owner, he attempts to lure in seven different female protagonists, each with distinct backgrounds, as customers.
Through repeated interactions, he gradually builds deeper emotional and physical connections with them.
Spoiler
In addition to managing the bathhouse for profit, players can venture into remote mountain areas to gather otherworldly herbs, craft special medicines, and sell them at high prices. There are also various other ways to earn money. Each in-game day is divided into four time periods, during which players can explore different areas, interact with various characters, obtain information, and engage in exchanges to improve income potential and increase favorability with the heroines.
If Ryouji’s illness is left untreated, he will collapse and be rushed to the emergency room the next day, resulting in a significant financial loss or even death. Players must constantly monitor his physical condition to avoid tragic consequences.

The game is a solid 6/10. Visual style and art is very good. Animated scenes are good. But the gameplay is mediocre and there is too little of full screen scenes. The top down, small sex scenes aren't really exiting…
