Conflict with Shinnosuke Nohara

Sugihara takes an interest in Shinnosuke after hearing that Inoue Ryushi has submitted to the first-year transfer student. He considers Inoue an embarrassment to the second-years and proposes teaching Shinnosuke a lesson under the pretext of showing a senior’s “care” 10.

The students he sends to deliver a message ruin Shinnosuke’s lunch and are beaten. Shinnosuke also makes one of them buy a replacement meal. Sugihara responds by kicking and berating his defeated men for failing even to deliver his message 13.

Distorted rumors soon claim that Sugihara himself was beaten, cried, or knelt before Shinnosuke. Furious, he storms into Class C. When Yasuda Takagi calls Shinnosuke “Big Brother Nohara,” Sugihara mistakes him for an underling and has him dragged to the rooftop, where he presents the badly beaten student to Shinnosuke 14.

Inoue and the Ryu Family interrupt the confrontation. Unsure he can defeat both opponents, Sugihara attempts to withdraw, but Shinnosuke stops him and promises that Inoue will not intervene 14.

Rooftop Defeat

Sugihara’s opening throw fails against Shinnosuke’s strength, and he is knocked into the rooftop fence. After recovering, he recognizes Shinnosuke’s lack of technique and successfully throws him using wrist control and a leg hook. Despite support from the judo club, Sugihara is eventually knocked unconscious by a punch that sends him crashing into a wall 15.

In the infirmary, he admits that he lost completely and might have fared even worse alone. However, he rejects Inoue’s suggestion that Shinnosuke could eventually lead them against Suzuran. Having once seen Bouya Harumichi, Sugihara regards Suzuran’s strongest fighters as far beyond their reach 16.

Training and Rematch

Sugihara resumes intensive training, fighting dozens of opponents at once and refusing to rest. By the time Shinnosuke publicly challenges Shinomiya Kai, Sugihara has slimmed down considerably. Hearing the challenge, he clenches his fists and leaves the judo club without speaking 24 32.

He later challenges Shinnosuke to a rematch under Shibukawa Bridge. Sugihara lands several attacks and dislocates Shinnosuke’s right arm, expecting to cripple his fighting ability. Shinnosuke resets the joint himself, resists a second attempt, and knocks Sugihara down with a punch 40.

Sugihara accepts the second defeat without his earlier fury. When Shinnosuke boasts that losing to him is nothing shameful, Sugihara instead wonders aloud how Inoue has tolerated him for so long 40.

Appearance

Sugihara is described as sharp-looking, although Shinnosuke contrasts that impression with his recklessness 21.

• Leaner build: Becomes considerably slimmer after sustained training 32.
• Changed bearing: Initially likened to a coldly gleaming spear; after training, his presence resembles a sheathed blade, with less openly displayed aggression 40.

Personality

Sugihara is proud, status-conscious, and easily provoked by humiliation. He treats Inoue’s allegiance to a junior as a disgrace to their year and reacts violently when his own reputation is damaged. Inoue explicitly identifies his concern with saving face as a major weakness 10 13 14 40.

His recklessness does not prevent him from recognizing danger. He considers retreat when Inoue joins Shinnosuke, acknowledges the scale of his rooftop defeat, and distinguishes Shinnosuke’s strength from the much greater power he attributes to Suzuran’s fighters 14 16.

Defeat also drives him to work harder. His refusal to stop training contrasts with his later willingness to accept another loss calmly, even when Shinnosuke speaks arrogantly to him 24 40.

Abilities & Skills

Judo

Sugihara has years of judo experience and uses grappling to exploit openings against physically stronger opponents 15.

• Performs shoulder throws and attempts throws using wrist and belt grips 10 15.
• Combines wrist control with a lower-leg hook to throw Shinnosuke 15.
• Provides the model for a throw Shinnosuke later uses against Satoshi Katagiri, explicitly crediting Sugihara 23.
• Can have his throws stopped when Shinnosuke prevents him from generating force 15 40.

Striking and Joint Manipulation

His fighting style includes attacks beyond conventional throwing techniques.

• Uses rapid punches, knee strikes, and roundhouse kicks 15.
• Launches kicks from crouching and hand-supported positions, including a two-footed attack toward the chin 40.
• Dislocates Shinnosuke’s right arm by manipulating his wrist at the instant his muscles relax 40.
• Fails to repeat the dislocation once Shinnosuke anticipates and resists it 40.

Combat Awareness and Endurance

• Recognizes during their first fight that Shinnosuke relies on speed and strength rather than developed technique 15.
• Recovers from being driven into a fence and continues attacking 15.
• Regains his footing after a heavy abdominal blow and continues the rematch despite spitting blood 40.

Relationships

• Shinnosuke Nohara — Rival who defeats him twice. Sugihara initially targets him to defend his standing as a senior, then trains intensely before seeking a rematch 10 15 24 40.
• Inoue Ryushi — Fellow second-year leader. Sugihara mocks his loyalty to Shinnosuke but respects his fighting ability enough to reconsider a confrontation; they later disagree over challenging Suzuran 14 16 28.
• Yasuda Takagi — Shinnosuke’s deskmate, whom Sugihara mistakes for an underling and uses as a beaten intermediary in the rooftop confrontation 14.
• Seki Kiriko — Fellow leading second-year. According to information Inoue gives Shinnosuke, Seki is substantially stronger than either Sugihara or Inoue 21 28.
• Judo club members — His followers and training partners. They support him against Shinnosuke, but he physically punishes members whose failed errand damages his reputation 13 15 24.
