Matsudai Sonoka

She is a 23-year-old freelancer. She is not very good at interpersonal relationships and often gives the impression of being vague, so she is not well understood and is often treated as eccentric.

Her family is wealthy and she is able to make a living without doing anything, but this position makes her life meaningless, and she leads a lethargic life where nothing lasts long.

She is not always apathetic, but has the pleasure of seeking sexual stimulation and is willing to do perverted things for it. However, she is still a virgin, as she is not interested in the kind of love and sex that requires a partner, as it is too much trouble.

Although she does not need to work, she spends her days working part-time at a brothel to satisfy her perverted desires and pass the time, depending on her mood.
