Extremely passionate. A 27-year-old coach who did not attend university. Currently holds a Beginner rank. Unbeknownst to him, his voice gets louder when he gets excited while speaking. He is energetic and very protective of his own skaters as well as others. He is an assistant coach at Lux Higashiyama FSC. He addresses females as -san and males as -kun politely. He is kind to everyone and was a huge fan of Jun Yodaka during middle school. Because his self-evaluation as a skater is extremely low due to past circumstances, he becomes notably dejected whenever that topic arises. He is very expressive, with his emotions showing clearly on his face, and the tears of joy he sheds whenever he sees his students grow are intense enough to fluster those around him.
