【Character Introduction】

Characteristics: High pride, elite, serious
Attributes: Hidden masochist, weak point is anal, has a desire to transform

Ritsuko is Akihiko's older sister and a 6-year veteran employee at a major company, often referred to as an elite employee. Recently, she has been entrusted with a large project, which has created a tense atmosphere around her. From before, she has been overly critical and nagging towards the sloppy Akihiko (in fact, she treats both Akihiko and Makoto the same way). This has been extremely painful for Akihiko, and he has come to avoid seeing her as much as possible. During her student days, she was focused solely on her studies, and even after graduating, she has had little romantic experience. She ends up deeply immersed in the hypnotic sex that Akihiko has set up for her.






Name: Narumiya Makoto
Height: 168 cm
Measurements: 121/58/85
Characteristics: Athletic, caring, proactive
Attributes: Masturbation lover, scent fetish, exhibitionist tendencies

She is the younger sister of Ritsuko and the other older sister of Akihiko. She is more athletically inclined and attends a prestigious university known for its sports programs. Her bright and straightforward personality, which often comes across as meddlesome, is seen as annoying and troublesome by Akihiko. However, she does not clearly dislike Akihiko, and her impression is more like "if only he could be a bit more put together." Similar to Akihiko, she is also often scolded by Ritsuko, but unlike him, the more adaptable Makoto is able to skillfully avoid those situations. She has a boyfriend named Kenji who is in the same year as her.
