Traditional Erotic Massage: Mother-Daughter Special Service

Kouta Morimura
Back in his school days, he was the strongest member of the judo club and even went on to score a gold medal in the nationals. As a result, he's got some pretty impressive physical strength.
After a chance encounter, he found himself joining the "Koiryu-kai" - a yakuza group.
Kouta's greatest weakness is his pervertedness. Once he sees a woman he wants, his urges take over.
After getting his hands on the girl of one of his higher-ups, he became a wanted man and fled to the countryside for a while. Now, he's back.
Yuusuke Kawashima, another member of the same group, has a soft spot for Kouta and has taken him under his wing, hoping to train him to take over one of his businesses.

Misako
The manager-cum-number one hostess of a bar called "En" in Yokohama.
After getting pregnant, she quit school.
When she resurfaced, the woman she had become was kind, outgoing, and great with people.

Kanon Nosaki
Misako's daughter.
Her parents split up when she was small and she went to live with her father.
However, her father was recently arrested and Misako has taken her in.
She's part of a biker gang, and though she appears strong-willed, she's actually quite soft and timid.

Eiko Matsushita
The lady of the house of the Matsushita Corporation. Her cold, arrogant aura is scary enough.
She loves the thrill of gambling.
She has two daughters - Ayana and Kanna.

Kanna Matsushita
Eiko's daughter.
She is a fresh high school graduate who has just started life as a university student.
Unlike her outgoing older sister, Kanna is quite shy and hopes to become like Ayana one day.

Youko Tanaka
Youko runs a struggling yoga studio and works part-time to gain management experience as she goes.
A man's woman, she does whatever she wants and is quite the drinker.

Miki Takanashi
The second daughter of the chief of the Koiryu-kai.
She's currently dating Yuusuke Kawashima, one of the higher-ups in the organization.
She has impressive managerial skills, can do pretty much any task you throw at her, and is fiercely independent.
She seems to harbor a little animosity towards Misako due to the ambiguous relationship between her and Yuusuke in the beginning.

Yuusuke Kawashima
A Koiryu-kai higher-up, leader of the Kawashima-gumi.
A businessman with a talent for making money, he has little interest in conflicts with other yakuza groups.
He's very fond of his underling, Kouta, who seems to exhibit a lot of the same qualities Yuusuke has.

Sayaka Amemiya
Sayaka is bright and great at her studies. She's working at the massage parlor so she can head overseas to study archaeology.
