Room 404: Erotic Massage PC (Final)

Relaxation, Massage, and a Hidden Identity

After a long and exhausting day, the clients arrive carrying plenty of tension. From tired feet to stiff shoulders, the goal is to help them unwind through a detailed massage experience.

Behind the ordinary appearance of a private massage parlor is a therapist with a very different specialty at Room 404: Erotic Massage. The business operates inside a multi-tenant building, attracting new clients with special offers and discounts.

This time, three women become the focus of the story: Sana, a university student finishing her company internship; Koharu, a busy office worker; and Rion, a quiet librarian.

The massage begins with smaller areas such as the hands and feet before gradually moving toward other parts of the body in Room 404: Erotic Massage. Players can apply oil, adjust their technique, and interact with different massage tools for a more detailed and immersive experience.

Three Clients, Three Different Personalities

Itou Sana

University Student (Company Intern) / 21 years old / 163 cm

Sana has a relaxed, easygoing personality and rarely becomes flustered. When something goes wrong, she has no trouble asking others for help.

Her slightly clumsy nature can sometimes create unexpected situations for the people around her. She also has a habit of getting lost in her own thoughts.

Hinata Koharu

Event Planning Company Employee / 25 years old / 161 cm

Koharu is cheerful, energetic in Room 404: Erotic Massage, and quick to make friends. She approaches challenges with a strong determination and does not give up easily.

At times, her enthusiasm gets the better of her. She may act before thinking things through and occasionally forget important details.

Shirakawa Rion

Librarian / 24 years old / 160 cm

Rion is polite, considerate, and naturally empathetic. She is a good listener and has a strong inner character, although she can be somewhat reserved at Room 404: Erotic Massage.

She sometimes keeps her feelings to herself and can be overly hard on herself. When it comes to romance, her shy personality becomes especially noticeable.
