Eiji's flexible body allows him to reach balls with a touch of flair that few can replicate. His dives and flips often astonish the spectators and often gets grudging praise from his opponents helping Eiji focus. He focuses on the net with his "Kikumaru Beam", a sharp volley that is hit with his hand reaching around his back, and his "Kikumaru Bazooka", a smash hit upsidedown. While playing doubles, Eiji follows the lead of Oishi. The two rely on and know each other thoroughly, which allows them to predict each other's moves without any signals. They further develop this by achieving "Synchronization", letting them act together as if they were only one person. He can also play well in singles by using his "Seal Step", which uses his speed to move from one location to a new one the moment the opponents eyes leave his first location. This gives the opponent the impression that there are two of him for a doppelganger type effect, though the anime gives him the ability to hug and high five his after image, making it slightly unrealistic.
