桐生 栄一

A man with an attractive face and figure, and a good grasp of things. He has lived smoothly just like what his parents expected of him.

However, because of his management incompetence, the company he inherited from his father is currently on the verge of bankruptcy.

Since his childhood, he has always completely looked down on his incompetent younger brother, but after knowing of Shinji's wealth, he planned on ripping off his brother's money.

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.
