Background

Tezuka had already embarked on his own tennis path by the time of the early JR Tournament, placing him ahead of players such as Sanada, who had not yet found an equivalent path. 1

Although he was initially interested in joining Seigaku, Tezuka ultimately entered Hyotei. Coach Sakaki recognized both his exceptional talent and his mastery of unusual techniques shortly after observing one of his matches. 30 51 Tezuka later became Hyotei’s club president despite Kamikawa Mutsu being acknowledged as the club’s strongest player. 194 507

At the JR Tournament, Tezuka reached the elementary division final against Kamikawa. He pushed himself to use Radiant Light against Kamikawa’s Dancing Golden Snake but lost 6–4, beginning a long-running rivalry defined by mutual respect and constant escalation. 20

Under Tezuka’s leadership, Hyotei won three consecutive National Tournament championships. 507 His own tennis continued to develop from a spin-centered Domain Technique into a complete personal system built on control, composite rotation, Zero techniques, and Muga no Kyochi. 399 413

Tezuka later joined Germany’s representative team and trained toward a professional career. Polch blocked an early attempt to turn professional, judging that Tezuka was not yet ready. 459 In the World Cup, he represented Germany against international junior-high opponents including Henry Nobel III, Romifel Fernandez, and Yukimura Seiichi. 476 507 535

Appearance

Tezuka is a left-handed player who wears gold-rimmed glasses and is frequently depicted carrying a racket. 26 536

• Gold-rimmed glasses. 26
• Left-handed playing style. 26 262
• Uses a silver-white racket during his Germany-team matches. 536
• Often manifests cyan, white, seven-colored, or crimson radiance when activating advanced techniques. 262 299 537

Personality

Tezuka is calm, disciplined, and intensely focused on tennis. He does not allow provocation to easily alter his outward demeanor, though Romifel’s psychological attacks reveal that his rivalry with Kamikawa is a deeply rooted source of pressure. 507 510

He carries strong pride as both a player and club president. Tezuka craves difficult matches and wishes to play against strong opponents even when Hyotei’s team lineup does not require him to appear. 123 His desire to win can become dangerous: against Kamikawa, he was willing to risk his wrist and future tennis career to use the Tezuka Phantom in a practice match. 299

Despite this intensity, Tezuka takes his responsibilities as captain seriously. He considers Hyotei’s long-term future rather than placing its hopes on a single successor, and he eventually accepts Kamikawa’s superior strength without resentment. 339 300 His recovery against Romifel is driven not only by fortitude, but by rediscovering the joy of playing tennis. 511

Abilities & Skills

Tezuka Zone / Domain Technique

Tezuka imparts controlled spin that draws opposing shots toward his preferred position, reducing the distance he must cover and allowing him to control rallies from the baseline. 123 158

• Draws powerful returns, slices, and many unconventional shots back toward Tezuka. 137
• Its earlier weaknesses against lobs and net slices were gradually repaired through training. 137
• Can be disrupted by accelerated net play, altered spin, and sustained pressure designed to break Tezuka’s rhythm. 90 158
• Evolves into a supreme Domain when combined with Seamless Clothes and composite spin. 511 536

Tezuka Phantom

An alternative Domain Technique that reverses the normal Zone’s effect, drawing shots outward and forcing them out of bounds. 299

• Requires substantially more spin than a standard Tezuka Zone. 299
• Can turn an opponent’s body shot or low return into an out ball. 299
• Places extreme strain on Tezuka’s arm and risks damaging his tennis career. 299

Zero-style Slice and Zero Serve

Tezuka’s Zero techniques use precise spin and placement to produce shots that roll back toward the net rather than rebounding normally. 18 413

• Zero-style Slice drops low, rapidly loses bounce, and rolls backward into the net. 158
• Can be used unexpectedly from mid-court after cross-court exchanges. 158
• Zero Serve is regarded as a professional-level serve and can be unreturnable without exceptional timing or a scoop return. 262 508
• Repeated use previously placed strain on Tezuka’s wrist, though Germany’s training improved his ability to maintain it. 298 537

Muga no Kyochi and Its Limits

Tezuka has opened the three doors of deep Muga no Kyochi: the Limit of a Hundred Refinements, the Limit of Bursting Talent, and the Limit of Seamlessness. 397 508

• Limit of a Hundred Refinements — strengthens his physical attributes and amplifies the power of his returns. 262 508
• Limit of Bursting Talent — enhances the inner self and manifests as intensified mental energy and radiance. 168 508
• Limit of Seamlessness — enhances Tezuka’s overall strength, places psychological pressure on opponents, and grants resistance to ordinary mental techniques. 381 508
• Seamless Clothes does not completely protect him from Romifel’s materialization, which attacks the inner self by means beyond ordinary mental interference. 510

Composite Spin

Tezuka’s mature tennis system uses simultaneous inward and outward rotation to produce more complex control than his original Domain Technique. 413

• Generates both inward- and outward-blowing vortices around the ball. 413
• Supports his supreme Domain and allows him to maintain pressure without relying solely on Seamless Clothes. 413 536
• Lets him integrate outside techniques, such as Kamikawa’s Dancing Golden Snake, into his own spin-based system. 539

Radiance of Pride

A dual-radiance state born from Tezuka’s fortitude and his joy in playing tennis. 511

• Breaks Romifel’s mental influence and materialized fears. 511
• Enables Tezuka to use two radiances simultaneously. 511
• Greatly suppresses opponents, including players who had believed the gap between themselves and Tezuka was manageable. 454

Equipment

• Tennis racket — Tezuka’s primary weapon; repeated high-level exchanges have damaged or destroyed his rackets, including during matches against Kamikawa and Sanada. 300 413
• Gold-rimmed glasses — his defining accessory. 26

Relationships

• Kamikawa Mutsu — Childhood friend, Hyotei’s ace, and Tezuka’s defining rival. Kamikawa’s continued superiority becomes Tezuka’s deepest internal pressure, but they also train together and push one another to improve. 20 299 510
• Atobe Keigo — Hyotei teammate and vice-captain. Atobe recognizes Tezuka’s leadership and repeatedly intervenes when Tezuka risks serious injury. 262 299
• Yukimura Seiichi — Rival whose strategic and mental tennis repeatedly tests Tezuka’s Domain, Muga, and Seamless Clothes. 89 158 535
• Sanada Genichirou — Rival who respects Tezuka’s potential and later vows to surpass him after losing 6–1. 17 413
• Akutsu Jin — Rival club president. Their National Tournament match forces both players to reveal their evolved styles; Tezuka acknowledges that Akutsu has forged his own tennis path. 262 264
• Sakaki Taro — Hyotei coach who recognized Tezuka’s talent shortly after he joined the club. 30
• Retrou — Tezuka’s coach on the Germany representative team, who supports him during the Romifel match and identifies his advancement toward the professional stage. 510 512
• Polch — Germany representative team leader who sees Tezuka’s potential but refuses to allow him to turn professional before he is ready. 459
