|Like his legendary father Nanjirou, the American-born Echizen is a gifted tennis player. He won four junior titles in America before arriving in Japan and is the only first-year to earn a regular spot in Seigaku's history. When Echizen first arrived at Seigaku, his tennis was a copy of his father. Tezuka Kunimitsu, who wanted Echizen to become Seigaku's next pillar of support, decided to become the catalyst for Echizen to evolve his game, mercilessly trashing Echizen in an off-campus match. Echizen's game hit a new height when he attained Muga no Kyouchi during an unofficial match against Kirihara Akaya. With this new technique, Echizen put himself on the map as one of few players who could potentially dethrone the Emperor Sanada Genichirou. Cornered by Sanada's Fuu Rin Ka Zan during the Kantou finals, Echizen overcame the odds and won the tournament for Seigaku. At the Nationals, Echizen continued to break down the nation's elites, including the King Atobe Keigo and Son of God Yukimura Seiichi, to propel Seigaku to Japan's No. 1. At the end of the series, Echizen is shown to have returned to America.
|Twist Serve - A serve that bounces toward the receiver's eye.
|Snake - This is basically a Buggy Whip Shot.
|Split Step - A step that increases speed and allows Echizen to change direction easily.
|Drive B - Echizen slides to the front of the court, jumps, and hits a return that quickly bounces twice. The bounce is also very high.
|Super Rising - Echizen returns the ball before it bounces to the highest point. As a result, his opponents have less time to react.
|Twist Spin Shot - It has incredible bounce, but the posture required to prepare for the shot can destroy Echizen's shoulder.
|Drive A - A return that is aimed at the face.
|Zeroshiki Drop Shot - A drop shot in which the ball rolls away from the returner after landing.
|Sky Inversion Drop Volley - Echizen jumps up and appears ready to smash. Then suddenly, while he is still in the air, he makes a 360 turn and hits a drop shot.
|Muga no Kyouchi - Echizen achieved this state during his match against Kirihara.
|Cool Drive - A smash that doesn't bounce.
|Drive C - A Cool Drive with half the amount of spin.
|Drive D - Two consecutive Drive B's.
|Echizen Zone - All returns are drawn back to Nanjirou. This is one technique that Muga no Kyouchi can't copy.
|Hyaku Ren Jitoku no Kiwami - One of Muga no Kyouchi's 3 doors. It spares the user the fatigue that results from using Muga no Kyouchi and allows the user to return shots with twice the power and spin. A requisite for this technique is the Echizen Zone. Echizen's mastery of Hyaku Ren exceeds Tezuka as he can gather the aura wherever he wants, whenever he wants.
|Saikikanpatsu no Kiwami - One of Muga no Kyouchi's 3 doors and a singles-only technique. The user gains the ability to foresee the outcome of a point.
|Ten-i Muhou no Kiwami - One of Muga no Kyouchi's 3 doors. According to Nanjirou, everyone is in Ten-i Muhou the very first time they play tennis. A player loses it as he becomes too preoccupied with winning and losing. It can be regained when he forsakes the outcome of the match and is simply having fun playing tennis.
|Samurai Drive - Echizen hits the ball onto the string that connects the net to the pole, cutting the ball in two halves.
