Description
Kippei Tachibana is a third-year student at Fudomine Middle School, where he serves as the captain, coach, and the sole third-year player on the tennis team. He is a tall, well-built young man standing 179 centimeters tall and weighing 67 kilograms, with a birth date of August 15. His appearance has been a visual marker of his personal journey. When first introduced at Fudomine, he is known for his shaved head, a style he adopted as a public symbol of atonement. Prior to this, he had long, messy blonde hair that reflected his wilder, more aggressive nature on the court. Before the National Tournament, he returns to this blonde hairstyle, signaling a reconciliation with his former self and a recovery of his lost power.

Tachibana's personality is defined by a profound sense of responsibility and a deep-seated kindness that shapes every aspect of his life. As the leader of the Fudomine team, he is a pillar of calm strength and strategic thinking, commanding immense respect and trust from his underclassmen, who are all in their second year. He is a natural mentor, known for his fairness and protective nature, having once stood up for younger players against an abusive coach and senior members. This action led to him and his teammates being punished, but it also forged the new, tightly-knit Fudomine tennis club from scratch. Beneath his composed and disciplined exterior lies a formerly explosive and untamed competitive spirit. He is a gentle and caring individual off the court, skilled in a wide range of domestic tasks; he is an accomplished cook who knows over a hundred recipes, excels at ironing and precise knife work, and has a particular fondness for Japanese and Chinese cuisine. He dislikes computers and sweets, and his interests include reading historical novels and listening to traditional Japanese taiko drums. When deeply focused in a match, he unconsciously slips into his native Kumamoto dialect.

Tachibana's motivations are rooted in his past as a national-level star from Kyushu. He was formerly the ace of Shishigaku, a top-four national school, where he and his best friend and doubles partner, Senri Chitose, were hailed as the "Two Wings of Kyushu." This ended tragically when Tachibana's powerful and aggressive shot accidentally struck Chitose in the right eye, causing a severe injury that threatened his friend's career. Overwhelmed with guilt, Tachibana abandoned his aggressive playing style, shaved his head, quit the tennis club, and transferred to Fudomine following his father's job relocation. His primary motivation is redemption. He initially suppresses his true power, adopting a cleaner, more controlled style of play, and dedicates himself to building a strong team from the ground up, partly as a way to atone for his past. Only after re-embracing his innate strength and facing Chitose on the court does he begin to truly move forward.

In the story, Tachibana's role is that of a formidable rival and a benchmark for national-level play. His team, Fudomine, is one of the key obstacles that Seishun Gakuen must overcome on their path to the Nationals. He is portrayed as a captain on par with Seigaku's Kunimitsu Tezuka, respected by his peers for his leadership and raw ability. He plays a crucial role in the character development of others, notably in an unofficial match where he effortlessly dismantles Shusuke Fuji's signature techniques, forcing Fuji to realize the gap between himself and national-level players and inspiring him to develop new, more powerful shots.

His most significant relationship is with Senri Chitose. This bond is a complex mix of fierce rivalry, deep friendship, and profound guilt. Their fated reunion in the quarterfinals of the National Tournament is a major character moment for Tachibana. He unleashes his true "Raging Lion" playing style, but even in the heat of the match, his care for Chitose is evident. He subconsciously avoids hitting the ball into Chitose's blind spot, the injured right eye, a fact his friend eventually realizes. Tachibana ultimately loses the match 5-7, but the battle serves as a form of atonement and allows him to reconnect with his former partner. His relationship with his team is that of a benevolent older brother. As the founder and captain, his leadership is the sole reason the current Fudomine team exists, and players like Akira Kamio hold him in the highest regard. His younger sister, An Tachibana, acts as the team's manager and is a constant source of support.

Tachibana's character development is a journey from violent, unchecked power to disciplined control and, finally, to a balanced integration of the two. After accidentally injuring Chitose, he completely rejects his former "violent" tennis, which weakens him and leads to a crushing defeat against the aggressive Akaya Kirihara at the Kanto Tournament. This loss, coupled with Chitose's comment that he has grown weaker, forces him to confront his past. Before the National Tournament, he regains his blonde hair and the "Beastly Aura," learning to channel his wild instincts with purpose and control. This evolution culminates in his match against Chitose, where he finally reconciles the two halves of his tennis identity, playing with full power while guided by his mature sense of sportsmanship and friendship. In the subsequent U-17 training camp, he continues to grow, achieving a "Beast-like Synchronization" with Chitose in doubles, a testament to their re-forged bond.

Notable abilities define Tachibana as a powerful and versatile player. He is an All-Rounder with immense power and high mental fortitude; official stats rate his power and精神力 at a maximum of 5 out of 5, while his speed and technique are rated at 3. His signature technique is the Wild Ball (Abare Dama), a deceptive shot hit off the frame of the racquet that causes the ball to vibrate and appear as if it has split into multiple trajectories. His true playing style, the Raging Lion (Abare Jishi), is a ferocious, hyper-aggressive offense that embodies his unleashed power. He can also harness the Beastly Aura (Moju no Aura), a state that enhances his physical abilities and gives him a feral, intimidating presence on the court. This aura eventually allows him and Chitose to achieve a form of doubles synchronization. Tachibana's game is a reflection of his character: initially a dangerous weapon of pure power, it is transformed through discipline and guilt into a controlled, strategic force that, when finally unleashed in balance, represents the full, formidable potential of a national champion.
