Description
Kunimitsu Tezuka is a third-year student at Seishun Academy, commonly known as Seigaku, and serves as the captain of the boys’ tennis team. He stands out for his reserved and highly disciplined demeanor, rarely showing overt emotion or engaging in casual conversation. Tezuka is defined by an unwavering sense of responsibility and a deep commitment to the sport of tennis, often placing the team’s success and the growth of its members above his own well-being.

His background includes early training in Germany, where he refined his skills and developed a professional-level technique. Tezuka suffers from a chronic left elbow injury, sustained during his first year due to overexertion and a previous conflict with a former senpai who injured him deliberately. This injury becomes a central element of his character, forcing him to balance his intense drive to play with the need to preserve his career. Despite medical advice, he continues to push his limits, particularly when facing strong opponents or when his team’s fate is at stake.

Tezuka’s primary motivation is to lead Seigaku to the national championship while ensuring that his teammates, especially the talented but raw first-year Ryouma Echizen, realize their full potential. He believes in victory through rigorous training, strategy, and mental fortitude. Unlike more flamboyant or expressive captains, Tezuka leads by example and through quiet authority. His famous phrase, “Don’t let your guard down,” encapsulates his philosophy of constant vigilance and effort.

Within the story, Tezuka acts as the stabilizing anchor of Seigaku. He is often the one to make difficult tactical decisions, such as altering the lineup for matches or imposing harsh training regimens to correct flaws in his players’ games. His role frequently involves both mentorship and confrontation, especially with Echizen, whom he recognizes as a future ace. Tezuka deliberately loses to Echizen in a non-official match to give the first-year a crucial lesson about the burden of leadership and the heights he must aim for. He also acts as a foil to other powerful players, such as Kunimitsu Oishi’s careful support and Sadaharu Inui’s data-driven logic, providing a more instinctive yet controlled force of will.

Key relationships include his doubles partner and vice-captain Kunimitsu Oishi, who frequently worries about Tezuka’s health and helps manage team morale. With Shuichiro Oishi (note: the previous name corrected; the reliable partner is actually Shuichiro Oishi), Tezuka shares mutual respect and an unspoken understanding. His rivalry with Seigaku’s coach, Sumire Ryuzaki, is not adversarial but based on trust; she often defers to his judgment on the court. Outside Seigaku, his most significant rival is Seiichi Yukimura of Rikkai University Affiliated Middle School, a captain of equal skill and leadership whom Tezuka respects deeply and has never beaten in a full official match due to injury.

Tezuka’s development is marked by moments of sacrifice and recovery. After a critical loss to Atobe Keigo of Hyotei Academy, where he aggravated his elbow rather than forfeit, he finally travels to Germany for rehabilitation. He returns stronger, having added new dimensions to his play, but continues to push his physical limits. By the end of the series, Tezuka achieves a resolution of sorts: he accepts the need to protect his body for a future in professional tennis, while still giving everything for his final national tournament.

Notable abilities center on his extraordinary precision and control. His signature moves are all pinpoint shots that exploit the opponent’s weaknesses. Tezuka Zone draws any returning shot directly to him, allowing him to control the rally’s pace and placement. Zero Shiki Serve is a short serve that bounces not forward but backward toward the net, making it virtually unreturnable. He also possesses a powerful drop shot, Zero Shiki Drop Shot, and high-speed counters such as Hyakuren Jitoku no Kiwami (the Pinnacle of Hard Work), which amplifies returning spin and power. Later, he attains the pinnacle of self-control, Tezuka Phantom, which curves the ball’s trajectory mid-flight but places immense strain on his elbow. These techniques reflect his philosophy: minimal wasted motion, maximum calculated effect.
