He is Tazusa's coach. He is an all around nice guy, always seeing the good aspects in everyone. Tazusa and her younger sister live with him because of their parents' divorce. In the beginning of the series, he had believed that the reason why Tazusa was hitting and torturing herself (although it was to hit and torture Pete) was due to stress of having Japan's representative figure skater in the Olympics being chosen soon. He also believes that whenever she is insulting Pete, it is him who is the target of her nasty remarks and also considers this as part of her stress. He reveals Hitomi as his fiancée on Episode 9.
