Background

Nagumo holds substantial influence in both the Student Council and the second year. As vice president, he effectively controls both vice-presidential positions through Kiriyama, a second-year Class B student who follows his direction. He has also expelled more than thirty students and brought the second year under his rule. 97 102

He first comes into direct conflict with Bai Lan after approaching Honami Ichinose. Nagumo recognizes Ichinose from her earlier Student Council application and introduces himself politely, but Bai Lan notices his interest in her and deliberately interferes. 95

Personality

Nagumo is status-conscious and highly protective of his authority. Being publicly dragged through the hallway by Bai Lan humiliates him because he believes appearing weak would invite second-year students to challenge his rule; he immediately responds with a threat of expulsion. 96 97

He is manipulative, patient, and willing to use others as disposable tools. His plan against Bai Lan involves recruiting moles from Bai Lan's class, isolating Bai Lan from potential allies, and arranging an expulsion at a moment when retaliation would be impossible. 132 133

Despite his ambition, Nagumo is prone to losing composure when personally challenged. Bai Lan's provocations repeatedly make him angry or fearful, eventually forcing him to prioritize avoiding further retaliation over punishing Bai Lan. 97 168 173

Abilities & Skills

Student Leadership and Influence

Nagumo maintains control through institutional authority, class influence, and private-point distribution.

• Dominated the second year after expelling more than thirty opposing students. 97
• Controls second-year resources and collects surplus private points through a “tax collection” model. 136 183
• Uses his authority to make subordinates dependent on his protection and fearful of abandoning him. 135
• Initially held influence over both Student Council vice-presidential positions through Kiriyama. 102

Manipulation and Scheming

Nagumo favors indirect retaliation when direct action could threaten his own position.

• Planned to recruit first-year students as moles, gradually turn Bai Lan’s classmates against him, and engineer Bai Lan’s expulsion. 132 133
• Targeted Kei Karuizawa because he considered her academically and physically vulnerable. 132
• Arranged a “hero saves the damsel” scenario around Karuizawa, first intending physical intimidation and later framing her for cutting in line so he could intervene as her savior. 132
• Attempted to protect Yonekura after her role in Karuizawa’s framing was exposed, fearing that abandoning her would undermine his ability to command others. 135

Athletic Ability

Nagumo possesses exceptional physical fitness and is a skilled soccer player.

• Dribbled past five opponents, deceived the goalkeeper, and scored during a soccer match. 165
• Bai Lan assesses his physical ability as among the school’s best, with fewer than ten students able to match or exceed it. 178
• Has sufficient pain tolerance and athletic conditioning to endure Bai Lan’s painful “treatment” while maintaining a composed public performance. 177 179

Deception and Damage Control

Nagumo can improvise under pressure when preserving his position is more important than appearing truthful.

• Denied Bai Lan’s public assault, claiming it was a misunderstanding in order to prevent Bai Lan from being expelled. 172 173
• Reframed Bai Lan’s attack during arbitration as medical treatment, even demonstrating a backflip to support the claim. 177 179
• Concealed the pain caused by Bai Lan’s technique to avoid giving Bai Lan grounds to pursue disciplinary punishment. 177 178

Relationships

• Bai Lan — Primary adversary. Their conflict begins after Bai Lan interrupts Nagumo’s approach to Ichinose, escalates through Karuizawa’s framing and a 50-million-point settlement, and continues after Bai Lan publicly assaults him. 95 143 166
• Honami Ichinose — A first-year Nagumo recognizes from her Student Council application and attempts to approach; Bai Lan interprets Nagumo’s interest as lecherous. 95
• Kei Karuizawa — Intended target for recruitment as a mole within Bai Lan’s class. Nagumo tries to manufacture situations in which he can become her protector and secure her loyalty. 131 132
• Yonekura — Accomplice in Nagumo’s plan against Karuizawa. Nagumo attempts to negotiate leniency for her after her role in the framing is revealed. 135 143
• Horikita Manabu — Student Council President and Nagumo’s desired rival. Manabu repeatedly intervenes when Nagumo loses control or attempts to use his authority recklessly. 97 177
• Kōenji Rokusuke — Injures Nagumo’s hand, leaving it broken for an expected minimum of three months. Nagumo later considers cooperating with Bai Lan to frame him. 219 220
• Kiriyama — The other Student Council Vice President, effectively subordinated to Nagumo’s influence over the second year. 102

Story Role / Major Arcs

Initial Conflict with Bai Lan

Nagumo approaches Ichinose on the rooftop stairs, presenting himself as a refined Student Council vice president. Bai Lan interrupts the encounter, drags Nagumo to the Student Council office, and publicly humiliates him. Nagumo responds by threatening Bai Lan with expulsion, beginning their rivalry. 95 96 97

Karuizawa Framing Incident

Seeking revenge without exposing himself to Bai Lan’s retaliation, Nagumo targets Karuizawa as a potential mole. He arranges the conditions for her framing, intending to rescue her publicly and gain both her trust and leverage over Bai Lan’s class. Bai Lan’s evidence exposes the scheme, however, and Nagumo is forced to compensate Karuizawa’s faction with 50 million private points. 132 134 143

The settlement requires a 15-million-point down payment, followed by monthly payments of 80% of Nagumo’s income, with daily interest of 0.1% until the debt is cleared. 143

Soccer Field Assault

While playing soccer to relieve pressure and reaffirm his confidence, Nagumo is ambushed by Bai Lan. Bai Lan punches him unconscious, continues the assault after he falls, evades Nagumo’s teammates, and leaves Nagumo severely injured in front of witnesses. 165 166

Nagumo learns that Bai Lan attacked several other students across multiple locations in roughly two minutes. Realizing Bai Lan has both overwhelming mobility and enough private points to nullify expulsion, Nagumo decides that preventing Bai Lan’s expulsion is safer than pursuing punishment. 167 168

Arbitration and “Treatment” Claim

During arbitration, Nagumo denies that Bai Lan assaulted him, attempting to avoid provoking further retaliation. When Bai Lan attacks again, Nagumo endures the pain and insists that Bai Lan is treating rather than harming him. 172 177

Bai Lan’s technique disperses blood clots and reduces Nagumo’s visible swelling, allowing Nagumo to make his claim more believable. 179

Broken Hand and Continued Debt

Nagumo later suffers a broken hand caused by Kōenji. The injury prevents Bai Lan from attacking him and is expected to require at least three months to heal. 218 220

Unable to escape the repayment agreement connected to Karuizawa’s framing, Nagumo asks Bai Lan to dissolve their arrangement. Bai Lan refuses, leaving Nagumo increasingly desperate and politically weakened. 220
