Kojirou Saeki
Saeki looks really laid-back and gentle, but looks can be deceiving, for he really is a very dangerous player. His talent for tennis is natural, and is accompanied by his above-average sight, which makes him even more difficult to beat. Saeki is also Rokkaku’s Vice-Captain, and like Aoi, seemed to be randomly selected by their coach. He also seems to know Fuji Shusuke and is good friends with him.
