Zero-Shiki (Degree) Drop shot. This shot causes the ball to roll away from the opponent and towards the net once it drops on their side of the টেনিস court (usually landing a foot away from the net), preventing them from hitting the ball again since it does not bounce toward them. He later develops a variation of this technique in the form of a serve called the Zero-Shiki Serve. Another one of Tezuka's signature techniques is the Tezuka Zone (手塚ゾーン Tezuka Zōn), a technique which involves him putting enough spin on the ball in order to force nearly all hits to be "sucked" into his hit zone, making it unnecessary for him to সরানো around the court. He is also able to use this technique so as to make the ball go out of bounds rather than toward him, with this being dubbed the Tezuka Phantom. However, in order to do this, Tezuka must create an even greater spin on the ball, which can result in Tezuka re-injuring his arm অথবা being permanently sidelined if he uses it consecutively.
Tezuka has also opened two of the three doors of Muga no Kyōchi (無我の境地, trans. State of Self Actualization), which is a technique in the series that can only be achieved when a টেনিস player reached and surpasses his limits. Tezuka's Tezuka Zone allows him to focus the effects of one of Muga's doors, Hyaku Ren Jitoku no Kiwami (百錬自得の極, lit. Pinnacle of Hard Work), into his left arm, preventing the loss of stamina, and giving him the ability to return balls with twice the strength, অথবা spin, that they were hit with. The Saiki Kanpatsu no Kiwami (才気煥発の極み, lit. Pinnacle of Great Wisdom) is another one of Muga's doors, which focuses the power of one's mind, giving him a form of foresight during the game.
