The series protagonist. A 25-year-old foreign cosmetics maker and elite salaryman. He was introduced to Yura through an omiai. He is very critical of his own sexual abilities, but that doesn't hinder him from having sexual fantasies with any pretty girl in his vicinity (ultimately, though, he stays faithful to Yura). Nevertheless, after his marriage he attracts the attention of a lot of female admirers.
