The protagonist who was always compared to his popular brother. He became an adult without ever trusting his own family. When he became an adult, he was jobless and living aimlessly, but after casually trying stock trading, his talents showed great results, and now, he's living alone comfortably. He couldn't accept that his childhood love Ayako married his hated brother, and ever since then, he hasn't came home. Madoka, who takes every chance to belittle Shinji as a worthless loser, always compares him to his older brother. Because of that, he never stopped resenting her. One day, when his brother asked him for a loan to save his company, he decided it was a good opportunity to steal everything from him.

The first love of the protagonist, and is a long time acquaintance to the Kiryuu household. She fell in love at first sight with the older brother Eiichi, then married him soon after. Also, she treats Shinji like her real little brother. Her kindness doesn't discriminate, and she also shows her husband the utmost respect by not talking back to him. She wants to have a baby soon, so she has sex with her husband every night, but even so, she still hasn't experienced orgasm. However, after she first tasted the pleasure given by her younger brother's penis, she started to become aware of her lewd side. Trying to protect her fidelity to her husband, she desperately tried to resist the pleasure, but... "Your sister's body will be the collateral, so please, I ask of you to finance our company."

The older sister of Ayako, and is the current secretary of Eiichi. She has earnestly loved Eiichi ever since they were children, but instead of her, Eiichi chose her younger sister as his bride. Even so, she convinced herself that Ayako is the household partner while she is the business partner. Shinji, who she has scorned all this time, raped her as if she was garbage when their situations reversed, with the company needing his money. Moreover, her pride, which hides her strong desire to depend on others, was seen through by Shinji, and thus her heart and body was trained to be that of a masochist's. "It's vexing... that I have to follow this worthless loser's orders!!"

He treats his wife Ayako like a beautiful trophy he won, and doesn't love her more than that. On the other hand, he uses the love that Madoka has for him to make use of her as his convenient woman, and as a substitute for Ayako.
