Kyouko is Kouta's sister-in-law. She married her older brother, but it is said he works overseas and he therefore lives alone with her. She is known as the "Venus of Track" due to both her beauty and her performance in track and field.
The Goddess's Sprinter
Takase is almost opposite of his brother - weak and bad at school. He recently moved in at his brother's house, who is a married guy. He is placed under an exceptional coach to improve his physical health, and the coach - also known as 'Venus of Track', is none other than his sister-in-law. She is developing a new technique to improve at a faster rate by managing testosterone levels in the body; in other words sexual desire management. She calls it 'absolute obedience'. And Takase has to go under it to improve himself.
