Background / History

Nagumo was originally placed in Class B and applied to join the Student Council during his first year. Horikita Manabu, then the Student Council vice president, was the only executive to oppose his entry. By his second year, Nagumo had risen to Class 2-A, accumulated nearly ten million Private Points, and established dominance over his grade. Students who resisted his rule had reportedly been expelled. 6 15

He expected to inherit the Student Council presidency after Horikita Manabu's graduation and viewed the incoming first-years as either potential assets or obstacles to remove. His influence extended through second-year Student Council executives, including Tonegawa Sosuke and Mizowaki Suito. 6 32

Ichinose Honami Incident

Nagumo summoned Ichinose Honami to the Student Council office after learning that Horikita had rejected her application. He exploited her insecurity over being assigned to Class B, secretly prepared a recording device, and persuaded her to confess that she had shoplifted a hair clip for her younger sister. He then offered her a Student Council position while intending to use her secret and her value as Class 1-B's central figure. 6

Suzuki Toru interrupted the meeting and threatened to publicize Nagumo's behavior and reputation. Facing the risk of scandal, Nagumo paid Suzuki one million Private Points for the recording and listening device. Ichinose subsequently rejected Nagumo's offer, refusing to become his “personal possession.” 7 8

Conflict with Suzuki Toru

Nagumo initially underestimated Suzuki after Horikita Manabu appointed the first-year as a Student Council vice president. When Suzuki began arranging Private Point-for-yen exchanges through badge contracts, Nagumo identified apparent weaknesses in the scheme and chose to intervene personally. 32 34 35

Nagumo altered the contract's terms to force Suzuki into a rapid cash payment, intending to claim ten million Private Points in damages or make Suzuki his “dog” if he defaulted. Suzuki had anticipated this response and produced Koenji Rokusuke as a witness and payment partner. Nagumo was forced to pay Suzuki four million Private Points, losing roughly half of his personal assets. 36 37

Following this defeat, Nagumo became more determined to retaliate against Suzuki. He accepted Katsuragi Kohei's apparent defection despite suspecting that Katsuragi was a spy sent by Suzuki, intending to use the arrangement against his rival. 37 46

Appearance

Nagumo is described as a fresh-faced, handsome young man whose smile and appearance readily attract attention. His usual demeanor is compared to that of a carefree playboy. 6 14

• Maintains a gentle, approachable smile when speaking with others. 6
• Has a cynical, unconstrained temperament that contrasts with Horikita Manabu's sternness. 14
• Is known among students for ambiguous relationships with multiple girls. 7

Personality

Nagumo is ambitious, status-conscious, and highly confident in his own ability. He values strength above all else and treats Advanced Nurturing High School as a hierarchy where weaker students should be removed. 8 46

He is a capable manipulator who researches others' vulnerabilities and uses authority, secrets, and Private Points to place them under his control. His treatment of Ichinose shows that he views talented people as assets to be collected and used rather than equals to be respected. 6 7

However, Nagumo's pride leaves him vulnerable to provocation. His desire to punish Suzuki and humiliate Horikita Manabu led him to force a contract confrontation without recognizing that Suzuki had designed the situation as a trap. 35 36 37

Strategic Contract Use

• He changed the contract's second clause to impose a cash-payment deadline on Suzuki. 36
• He attempted to convert a breach penalty into a claim for ten million Private Points. 36
