Background / History

Sanada is driven by Rikkai Dai’s goal of a third consecutive championship. After witnessing Horio’s strength, he immediately calls for harsher training and warns Kirihara against slacking off, reflecting the pressure he places on both himself and his team 49.

During Yukimura’s medical treatment, Sanada effectively carries the club’s responsibilities as vice-captain. This experience makes Tezuka regard him as the appropriate person to test Seigaku’s prospective next captain 227.

His failure to stop Kirihara’s harmful Red Eye tennis becomes a defining issue in his match with Horio. After Rikkai Dai’s Kanto Tournament loss, Sanada apologizes for Kirihara’s behavior and accepts Horio’s warning against using tennis to hurt others 89 92.

Personality

Sanada is stern, proud, and intensely committed to winning. He demands serious effort from teammates and reacts sharply when he sees what he considers disrespectful or lax tennis, such as Kaitou competing while wearing training weights 49 243.

His determination can become emotional instability under pressure. Tanegashima’s repeated counters leave him agitated enough to make mistakes against his own doubles partner, Akutsu 339. Even so, Sanada does not abandon matches: he played through a knee injury against Horio and continued fighting despite exhaustion 90 92.

Over time, he becomes more considerate of leadership and responsibility. His match against Kaitou begins as Tezuka’s requested test, but ends with Sanada sincerely acknowledging Kaitou’s potential and offering advice on what a captain must be 227 248.

Abilities & Skills

Wind, Forest, Fire, Mountain

Sanada’s core technique set combines speed, offense, defense, and tactical endurance.

• Swift as the Wind — a near-invisible, extremely fast serve and movement technique; even spectators struggle to see his swing 88.
• Aggressive as Fire — a flame-like aerial strike with enough force to knock Kaitou’s racket away 243.
• Immovable as a Mountain — creates a mountain-like defensive barrier; Sanada uses it to neutralize Kaitou’s Snake Shots and force a draining war of attrition 243.
• Forest — used in an attempt to counter Horio’s Shatter, though it proves ineffective 92.

Lightning

Sanada can strike with Lightning, later completed as Moving Like Thunder.

• He first uses an incomplete Lightning while injured, scoring points at the cost of worsening strain on his knees 90.
• The completed Moving Like Thunder counters Kaitou’s Wave Tornado Snake Shot and finishes their match 248.
• He also employs Lightning to destroy an obstructing iron gate during the U-17 conflict 276 278.

State of Selflessness

Sanada can enter the State of Selflessness, though he had previously sealed it because of its heavy stamina consumption 247.

• He reproduces the Tezuka Zone while in this state, pulling Kaitou’s returns toward himself and forcing Kaitou across the court 247.
• He combines the state with a Zero-style Drop Shot against Kaitou 247.
• Its sustained use leaves him breathing heavily and visibly exhausted 247.

Black Aura and Black Dragon

Sanada’s rage develops into a controlled black Aura rather than overwhelming his judgment.

• A black aura with dark-red traces manifests during his match against Kaitou and suppresses Kaitou’s Demonization 247.
• During multi-ball training, his rage evolves into a black Aura that enables him to return nine simultaneous balls 316.
• The Aura later develops into a black halo, strengthening his Swift as the Wind Storm 342.
• Black Dragon First Slash changes direction after its initial spin, allowing Sanada to trouble Tanegashima’s Extinguished Zero 341.
• Black Dragon Triple Slash is used as a follow-up offensive technique against Tanegashima 342.

Evolved Wind-Forest-Fire-Mountain

Sanada’s mountain training advances his foundational techniques.

• Wind evolves into Storm, substantially increasing his speed 316.
• Mountain evolves into Peak, reinforcing his defensive presence 316.
• He later employs the evolved suite as Storm Forest Flame Peak, though Tanegashima successfully reads and returns it 339.

Relationships

• Yukimura — Rikkai Dai’s captain; Sanada supports his team during Yukimura’s treatment and receives his match assignments in the national finals 227 242.
• Tezuka Kunimitsu — rival and fellow leader. Tezuka asks Sanada to test Seigaku’s future captain, and Sanada agrees despite their schools facing one another in the finals 227.
• Kaitou — Tezuka’s chosen captain candidate. Sanada initially pressures him harshly, then acknowledges his strength and offers leadership advice after winning their match 242 248.
• Horio — opponent, later trainer at the U-17 camp. Horio defeats Sanada in the Kanto Tournament and pushes his later evolutions through multi-ball practice 88 92 316.
• Kirihara Akaya — junior teammate whom Sanada trains strictly and expects much from; Sanada is criticized for having failed to stop Kirihara’s earlier harmful tennis 49 89 261.
• Yanagi Renji — Rikkai Dai teammate and longtime observer of Sanada’s techniques, including his return to the State of Selflessness 49 247.
• Atobe Keigo — rival who challenges Sanada to a private captain-versus-captain match after both feel pressure from Horio and Tezuka 98.
• Akutsu Jin — U-17 doubles partner. Their clashing temperaments initially hinder them, but they eventually cooperate against Tanegashima and Ohmeguro 339 340 342.

Story Role / Major Arcs

Kanto Tournament: First Singles vs. Horio

• Sanada opens with Swift as the Wind in an attempt to end the match quickly, only for Horio to return it immediately 88.
• Horio breaks Sanada’s key techniques, uses Shatter to cause intense pain and break his racket, then targets Sanada’s knee in retaliation for Kirihara’s treatment of Fuji 89 90.
• Sanada responds with incomplete Lightning despite the danger to his injured knee, but ultimately collapses from exhaustion as Seigaku defeats Rikkai Dai 90 92.
• Afterward, he apologizes for Kirihara’s actions and promises a future rematch with Horio 92.

Youth Training Camp: Rivalry with Atobe

• Sanada and Atobe arrange a private match after recognizing Horio and Tezuka as rivals who have raised the standard around them 98.

• Sanada overwhelms Kaitou early with invisible swings, Swift as the Wind, and Aggressive as Fire 242 243.
• Angered by Kaitou’s weighted training bands, he uses Immovable as a Mountain to exhaust Kaitou in a prolonged rally battle 243.
• His pressure contributes to Kaitou’s Demonization, forcing Sanada to activate Selflessness, the Tezuka Zone, and his black Aura 244 247.
• Sanada wins 6–2 with Moving Like Thunder, then explains that a leader must remain fearless and strong enough to guide the team 248.

U-17 Training Camp

• He later partners with Akutsu against Tanegashima Shuji and Ohmeguro Ryuji. Their early lack of coordination improves into genuine cooperation, but they ultimately lose to the first team 339 340 344.
