Yamabuki Chuu is a 1st year student at Class 1, with a shoe size of 24 cm. He uses his allowance to buy notebooks and pens. His contribution to the team has been significant since he first worked as Yamabukis manager. After learning from Seigakus Echizen that height is not important in tennis, he decided to focus on improving his play style and joined the team. Yamabuki Chuu is known for being a kind-hearted person who always says "-dadadadan!" when he gets excited.
