Yuna Saeki / 21 years old, Early Recovery Stage. 156cm. Feminine, curvy build. Compulsive sexual behavior disorder (exhibitionism and sexual intercourse). Currently on leave from university. Raised in a household where she received "sexual gazes" instead of affection since childhood, leading her to link the need for validation with sexual contact. She entered the home after reaching her physical and mental limits through repeated encounters with strangers on social media. While she understands intellectually that she is "ill," it hasn't fully sunk in yet, and she is hit by strong impulses from minor triggers (smartphones, gazes when going out, etc.). As the youngest in the group home, she oscillates between being clingy and rebellious toward other residents. She has just begun diary therapy and individual interviews with staff.

Maho Takahashi / 24 years old, Mid-Recovery Stage. 160cm. Curvy, glamorous build. Sexual addiction (masochism and self-pleasure). Former apparel sales clerk. In romantic relationships, she tends to suffer domestic violence and emotional abuse, repeating a pattern where "being controlled" is linked to sexual arousal. Through cognitive behavioral therapy, she has become able to verbalize the triggers for her impulses, but she still faces the risk of relapse, such as contacting an ex-partner on social media during overnight stays. She is becoming a mentor figure for Yuna within the home, and a tendency toward "caretaker addiction"—trying to maintain self-esteem by taking care of others while neglecting her own recovery—is starting to show.

Ayaka Morishita / 29 years old, Late Recovery Stage. 158cm. Average build. Sexual addiction (female-oriented brothels and swinging). Formerly worked as a nurse, but fell into using sex services and having relationships with many strangers as a way to vent stress from overwork, leading to the loss of her job. She has better emotional control than before and has acquired skills to cope with impulses through exercise and breathing techniques. On the other hand, she tends to hide her true feelings from staff by over-acting the role of the "cured self," and her perfectionism is becoming a hindrance to recovery. Facing an upcoming internship for re-employment, she is dealing with the anxiety of increasing contact with society.

Risa Ogawa / 31 years old, Near Discharge. 162cm. Curvy, glamorous build. Sexual addiction (intense self-pleasure and exhibitionism). She has been in the home the longest of the four. She was previously married, and her addictive behavior worsened as a way to fill her self-esteem after her husband's infidelity. After over a year of treatment, she has acquired techniques to distance herself from impulses, and her post-discharge life plan (work, housing, continued outpatient treatment) is concrete following vocational support. She is a "senior" figure relied upon by other residents, but she harbors anxiety that she might repeat the same behaviors once she is alone, alongside her expectations for discharge. She is in a position likely to be the POV character for the final social reintegration part.
