Background / History
Sanada began playing tennis at age four, giving him far more experience than most players in the elementary division. At the JR Tournament, he regarded Yukimura as his only worthy opponent and carried himself with the arrogance later associated with Rikkai Dai’s Emperor. 2 9
His A-group final against Tezuka became a formative defeat. Unable to break Tezuka Zone, Sanada recognized the difference in their strength and later underwent a major change in temperament following that loss. 9 183
After being shut out by Kamikawa, Sanada isolated himself at home and devoted himself to kendo training, to the point that Yanagi feared he might abandon tennis. He ultimately returned to Rikkai Dai with a stronger physique, more solid aura, and a more developed tennis system. 186 372
Appearance
Sanada is identified by deep blue hair and a headband in his early appearance; as Rikkai Dai’s vice club president, he is typically seen in a black baseball cap. 2 72
- Deep blue hair 2
- Green headband during the JR Tournament 2
- Black baseball cap as Rikkai Dai’s vice club president 72
- Frequently lowers his cap’s brim before serving or entering a serious state 2 370
Personality
Sanada is intensely proud, disciplined, and confrontational. He prefers direct competition and considers victory the foundation of all achievement, approaching every serious match as a test of whether his tennis can overwhelm the opponent head-on. 2 381 413
Defeat does not diminish his resolve. His losses to Tezuka, Atobe, and Kamikawa drive him into harsher training rather than resignation, though his fixation on victory has repeatedly led him to endanger his body through Swift as Lightning. 153 372 413
Despite his severity, Sanada is attentive to Rikkai Dai’s future. He recognizes Akutsu’s exceptional talent, encourages Kirihara to join the club, and sees his younger teammate’s arrogance as a reflection of his own past. 147 183 184
Abilities & Skills
Furinkazan
Sanada’s central tennis system combines offense, defense, placement, and speed. Its techniques function through mutual support and mutual restraint rather than as isolated moves. 188 230
- Swift as the Wind — An ultra-fast swing and return that opponents often cannot see clearly enough to judge its landing point. 105
- Calm as the Forest — A low, controlled shot that drops rapidly near the net. 188
- Aggressive as Fire — A powerful smash used to punish openings created by his speed and placement. 75 187
- Immovable as a Mountain — A defensive stance that lets him endure heavy rallies and stabilize himself after attacking. 106 230
- The system later evolved into Raging Forest Blazing Peak, with greater speed and offensive pressure. 363 370
Swift as Lightning / Thunder
Sanada’s signature burst-speed technique, also referred to as Thunder, allows him to reach and strike balls before opponents can react. 153 228 230
- Can intercept shots aimed at his blind spots and return them at extreme speed. 153
- Its repeated use places extreme strain on his legs and knees. 153 187

- Its evolved form, Swift as Mad Thunder, compresses the ball and delivers a faster, more penetrating return. 372 413
Unfathomable as Shadow
A later technique within Sanada’s expanded system, used to score against Tezuka during their main-tournament singles match. 411
- Tezuka characterizes Sanada’s mature system as Wind, Forest, Fire, Yin, and Thunder, built around his direct sword-fighting philosophy. 413
- Sanada uses its black aura and thunder-infused returns to challenge the Limit of Seamlessness. 412 413
Kendo-Integrated Tennis
Sanada’s kendo practice informs his stance, grip, and striking motion. His tennis increasingly resembles a swordsman’s direct slashing attacks. 182 360 411
- Kendo training strengthened his grip and enabled heavier, more forceful smashes. 411
- He fully incorporated sword-wielding slashes into Furinkazan against Tachibana. 360
- His philosophy favors overwhelming the opponent through continual, uncompromising offense. 413
