OVA
Description
Gin Ishida is a third-year student at Shitenhoji Junior High School and a regular member of its powerful tennis team. Known as the physically strongest middle school player in the series, his appearance is striking and memorable. He is notably tall for his age, standing at 189 centimeters, with a large, muscular build and a completely bald head. This appearance, combined with his calm and serious demeanor, often leads to humorous situations where elderly people mistake him for the Buddha or a monk. His nickname among fans and peers is Master Gin, a title that reflects his disciplined and revered presence on and off the court.

Gin's personality is a study in contrasts. Off the court, he is a person of few words, exhibiting a calm, polite, and deeply respectful nature. He often performs gestures associated with Buddhism, such as pressing his hands together in prayer before and after matches. This has earned him the image of an ascetic or a monk. He lives a disciplined life, with hobbies that include rigorous training, seated meditation known as zazen, and reciting the Heart Sutra, which is one of his non-tennis special skills. However, once he steps onto the tennis court, this serene exterior gives way to a fierce and relentless competitor. He operates on a personal philosophy that showing mercy or holding back against an opponent who is giving their all is a sign of disrespect. This belief leads him to fight with overwhelming force, not out of cruelty, but out of a deep respect for the spirit of the game and his adversary.

Gin's primary motivation in tennis is centered on the mastery of power and the perfection of his signature technique, the Hadokyu. He is credited as the creator of the Hadokyu, a devastating series of power shots with 108 escalating levels of destructive force. His younger brother, Tetsu Ishida from Fudomine Middle School, learned this technique from him. Gin's goal is to reach the pinnacle of this power, and he sees matches as a test of will and physical极限. He is driven to challenge himself against opponents who can withstand his strength, pushing both himself and his rival to their absolute limits, even if it results in mutual destruction.

In the story, Gin serves as a major obstacle representing the pinnacle of physical power in the national tournament. His most significant role is during the Nationals semifinal match against Seigaku's Takashi Kawamura. In a brutal Singles 2 match, Gin completely dominates with his Hadokyu, but his refusal to relent and Kawamura's refusal to give up result in a shocking conclusion. On match point, Kawamura's desperation shot, a mishit that generated even more power than Gin's 108th Hadokyu, fractures Gin's arm, forcing him to forfeit the match. This event demonstrates his crucial role not just as a powerful player, but as a catalyst for other characters' growth. Later, in the U-17 training camp, he continues to serve as a benchmark for power. He loses decisively to Duke Watanabe, the top power player among the high school representatives, in a match that showcases the vast gap between middle school and the national team's elite.

Gin's key relationships are defined by respect and rivalry. His most significant familial bond is with his younger brother, Tetsu Ishida. Gin taught Tetsu the Hadokyu, and they face each other as opponents in a doubles match during the National Tournament quarterfinals. His most famous rivalry is with Takashi Kawamura. Their match in the semifinals is a legendary clash of power where both players retire due to injuries sustained from the other's shots. After the match, the typically stoic Gin showed his caring nature by immediately inquiring about which hospital Kawamura was taken to, showing respect for the opponent who pushed him to his breaking point. At the U-17 training camp, after losing to Duke Watanabe, the two form an unexpected bond. They later become partners for a power-focused doubles pair representing Japan in the U-17 World Cup.

Gin undergoes notable development from the original series to the sequel, The New Prince of Tennis. In the original story, his role is largely that of an unbeatable force who is ultimately undone by his own power and the spirit of a lesser opponent. At the U-17 camp, he is humbled by Duke Watanabe, realizing there are levels of power far beyond his own. This experience motivates him to grow further. By the time of the U-17 World Cup, Gin has evolved his abilities, developing a new technique called the Ura Hadokyu, or Reverse Hadokyu, which allows him to pull the ball with spin rather than just pushing it with raw force. This effectively doubles his arsenal, implying he now has command over 216 variations of his signature shot. This development shows his ability to adapt and learn from his defeats.

Gin's notable abilities center almost entirely on overwhelming power. His playing style is classified as an Aggressive Baseliner, a strategy built on dominating from the baseline with powerful groundstrokes. His statistics from the U-17 camp reflect this specialization, with a maximum score of 5 in both Power and Mental strength, offset by very low scores of 1 in Speed, 2 in Stamina, and 2 in Technique. His signature technique is the Hadokyu, which has 108 levels. A Level 1 Hadokyu is said to be equal in power to Takashi Kawamura's Dash Hadokyu, while the maximum 108th form is a shot of incredible destructive force. In addition to unleashing these powerful shots, Gin has also developed a defensive technique that allows him to completely neutralize an incoming Hadokyu, sending it back as a plain, normal shot to his opponent. His physical strength is immense, demonstrated by his ability to bench press over 200 kilograms.
