Background

Makoto is a transmigrator who began his first day at Advanced Nurturing High School without memories of the original body’s owner. Rather than panic, he immediately observed the school’s systems and deliberately left indirect clues about its hidden rules for other students to find. He also encountered Ayanokoji Kiyotaka and Horikita Suzune at a convenience store that day. 1

He initially considered himself only slightly above average among the first-years without his knowledge of the original story, and consciously avoided making enemies of exceptional students such as Ayanokoji and Sakayanagi Arisu. 33 His familiarity with future events and important students nevertheless became a major advantage in his early maneuvering. 89

Makoto’s unknown personal background gradually becomes a source of concern. Sakayanagi Kōhei and Sakayanagi Arisu treat his family name as significant, while Yagami Takuya later identifies Naoe Haruhiko as Makoto’s older brother. Makoto also learns that his father has been observing his performance from outside the school; the Naoe Conglomerate is a school backer, though school rules prevent Makoto’s family from directly intervening in his affairs. 123 125 232 248 249

The Naoe Conglomerate also has a representative on the school’s Board of Directors. Despite these connections, Makoto remains dependent on his own preparations and alliances within the school rather than direct family protection. 249

History

Makoto encouraged Ichinose Honami to seek a Student Council post, reasoning that her academic, interpersonal, and strategic strengths made her the best public candidate. He later applied as well; Horikita Manabu approved both applications after recognizing Makoto’s potential and his lack of Nagumo Miyabi’s arrogance. 6 9

As a first-year, Makoto built influence through alliances and information. He cooperated with Sakayanagi against Katsuragi, accepted Hoshinomiya Chie’s paid assignment to monitor Class D, and made a non-aggression arrangement with Ayanokoji to keep him from actively elevating Class D against Class A. 17 20

He led his class through the Uninhabited Island Exam, serving as leader, scouting resources and bases, and coordinating with Ichinose and Kanzaki. His measurable contribution exceeded 350 class points, helping Class A secure victory. 57 73

During the exam, Makoto saw through Ryuen’s layered leader-card deception by tracking Class C’s movements through heavy rain. He intercepted Shiina Hiyori before she could become Ryuen’s final variable, withdrew alongside her, and became Class D’s replacement leader to reduce the penalty caused by Horikita Suzune’s exposure. 65 66 67

After gaining prominence during the island exam, Makoto was promoted to Student Council Vice President. He openly challenged Nagumo’s pressure, assembled a first-year team to defeat Nagumo’s in pool volleyball, and later defeated him in the Sports Festival’s final relay. 98 104 106 122

Makoto eventually weakened Nagumo’s position with support from Sakayanagi Kōhei and allied students. Following Nagumo’s decline, he succeeded Horikita Manabu as Student Council President without opposition, appointing Kiriyama Ikuto and Ichinose Honami as vice presidents. 124 142

During the Mixed Training Camp, Makoto separated from his class and led a mixed group to draw Nagumo’s attention away from Class A. He also began intensive self-defense training with Ayanokoji and Kanzaki in preparation for White Room students entering the school. 184 191 198

When Class A faced a financial crisis and a direct special exam against Sakayanagi’s Class B, Makoto spent 20 million private points to bring Katsuragi Kohei into Class A. In the subsequent Selection Project Special Exam, he acted as Class A’s Command Tower, revised the mental-arithmetic rules to limit Sakayanagi’s intervention advantage, and coordinated with her during the final chess match to secure Protection Points despite Class A’s overall loss. 217 223 225 226

Horikita Manabu’s promise to transfer the 37 million private points saved by his graduating class provided the financial security Makoto needed to proceed with Katsuragi’s recruitment. Makoto appealed to Katsuragi’s ability, compatibility with Class A’s ideals, and desire to challenge Sakayanagi after Totsuka Yahiko’s expulsion. 217

Makoto noticed that Acting Chairman Tsukishiro had interfered with the Selection Project’s final instructions and deduced that Tsukishiro intended to have him expelled. Rather than retreat, he and Sakayanagi prepared for further attacks on the Command Tower. 227 231

After the new first-years arrived, Makoto identified the White Room threat surrounding Ayanokoji. He allowed Tsukishiro’s 20-million-point bounty on Ayanokoji to proceed as bait for the hidden assassin, while using public controversy and controlled information leaks to make the operation credible. 233 247 248 249

During the controversy surrounding Kushida’s past, Makoto released evidence he had retained since the previous October implicating Sudo Ken and Ike Kanji in Sotomura Hideo’s attempt to secretly film the girls’ restroom. Their subsequent expulsions reinforced the risks of targeting Makoto or Ayanokoji. 235 237

Makoto later anticipated Hosen Kazuomi’s attempt to lure Ayanokoji into an unrecorded confrontation. Armed with decisive recordings of Hosen’s knife attack, he compelled Hosen to cooperate with Horikita’s class and form a team with Ayanokoji rather than face expulsion. He subsequently defeated Nanase Tsubasa in a controlled fight, proving the extent of his combat growth. 261 264

After the fight, Makoto urged Nanase to reconsider her revenge and offered her the choice of leaving school or joining his side. By the preparations for the next island exam, he had assigned her to monitor first-year movements and warn Ayanokoji about suspicious activity. 265 274

Before the second-year Uninhabited Island Special Exam, Sakayanagi challenged Makoto to a proper competition, supported by her B-Class and D-plus-Class alliance. Makoto initially considered remaining independent and using his Recruitment Card flexibly, with the safety of Kushida, Sato Maya, and other potential targets taking priority. Ayanokoji’s decision to protect Sato and later merge with Kushida’s group allowed Makoto to accept Sakayanagi’s challenge. 275

Makoto entered the island exam with a plan to join Kanzaki’s boys’ group through his Recruitment Card. He subsequently worked with Kanzaki, Katsuragi, and Hirata Yosuke, dividing movement orders and Challenges among them according to location and ability. His own attempt at the Anime Knowledge Quiz ended without a reward, demonstrating the limits of his knowledge of this world’s entertainment. 280 286 288

As the exam progressed, Makoto anticipated that Tsukishiro’s side might resort to injuring participants or their teammates to force withdrawals. He later learned that Komiya and Kinoshita had been attacked and forced to withdraw, with their appeal rejected because the GPS records showed no other person at the scene. Mashima also privately warned him that Tsukishiro had arranged an additional rescue speedboat and was patrolling the island daily. 288 295 299

Makoto merged his group with Ichinose’s, bringing their membership to seven. The enlarged group recovered to sixth place, then reached first place on day five after Makoto and Onodera Kayano each won an Open-Water Swimming Challenge worth 20 points. 299 300

Alongside the competition, Makoto collaborated with Tsubaki Sakurako and Utsunomiya Riku against Yagami. Nanase left Hosen’s group to travel with Ayanokoji as part of Makoto’s protective arrangements. His cooperation with Tsubaki eventually removed uninvolved first-years from the confrontation, narrowing the remaining threat to the White Room students. 293 300 309

At the island confrontation, Makoto refused Tsukishiro’s demand for cooperation. When Yagami attacked him, he defended while retreating toward the forest, where Utsunomiya was concealed with a deliberately broken GPS watch. Makoto had also hired Kiryūin Fūka as backup for Ayanokoji; she agreed to delay Sima while Ayanokoji confronted Tsukishiro. With Utsunomiya’s assistance, Makoto shifted from defensive evasion to coordinated attacks against Yagami. 311 312

Makoto’s group ultimately won the island exam with 306 points. The first-place reward and Trial Card bonus produced 450 class points, split equally with Class C, giving Class A 225 points. His performance in the Challenges and confrontation with Yagami also raised his OAA overall evaluation to A (90), making him the school’s first student to achieve an A-grade overall rating. 316

Personality

Makoto is observant, cautious, and highly pragmatic. He recognizes his own shortcomings and prefers to secure cooperation with powerful people rather than challenge them recklessly. 33 66 He is capable of concealing his intentions behind a calm, friendly demeanor and often uses school rules, contracts, secrets, and social pressure to control situations. 17 22 84

His methods can be manipulative: he coerced Kamuro Masumi and Kushida Kikyo using their secrets, planned attacks on Class D, and treated information as a resource to be traded. 18 22 78 However, he also avoids needless cruelty. He declined to immediately expel Ryuen despite holding decisive evidence against him, acted fairly during inter-class disputes, and repeatedly helped students such as Sakura Airi, Karuizawa Kei, and Horikita Suzune address their personal problems. 45 86 88

Makoto is willing to assume responsibility for the trust his classmates place in him. He views leading them to graduate from Class A as an obligation created by the authority they granted him. 157

He is increasingly confident when confronting hostile forces, but remains careful not to mistake confidence for invulnerability. He turned Tsukishiro’s bounty into bait for White Room students, restrained Hosen through negotiated conditions rather than expulsion, and deliberately tested Nanase’s resolve without seriously injuring her. 248 261 264

Protecting vulnerable allies can take precedence over pursuing a competitive victory. Before accepting Sakayanagi’s island-exam challenge, he focused on the danger White Room agents posed to students associated with Ayanokoji, rather than doubting Ayanokoji’s ability to defend himself. 275

Makoto remains composed when his preparations do not produce the desired result. He accepts his failure in the Anime Knowledge Quiz without resentment and recognizes the winner’s superior specialized knowledge. His humor also persists under pressure, including banter about hot-blooded manga during the confrontation with Tsukishiro. 286 311

He increasingly treats ordinary school experiences and emotional relationships as meaningful influences on Ayanokoji. Unable to determine Ayanokoji Atsuomi’s full intentions, Makoto seeks to encourage Ayanokoji’s emotional development rather than merely protect his competitive position. 265 314

Abilities & Skills

Strategic Analysis

Makoto rapidly identifies systems, hidden incentives, and exploitable rules.

• Deduced the school’s early point and meal systems, then revealed them indirectly rather than openly breaking rules. 1
• Identified unusual patterns in second-year class-point totals and inferred that Nagumo had already begun manipulating the year’s competition. 8
• Anticipated Ishizaki Daichi’s collision during the Sports Festival obstacle course and arranged for evidence to expose the foul. 118
• Recognized Ayanokoji’s concealed ability and negotiated a cooperation agreement before Class D became a direct threat. 20 53
• Identified Ryuen’s multi-layered leader-switching scheme during the Uninhabited Island Exam by following the timing, movements, and withdrawals of his operatives through heavy rain. 65 66
• Detected Tsukishiro’s alteration of the Selection Project’s final instruction and inferred that the acting chairman’s objective was his expulsion. 227
• Allowed the bounty on Ayanokoji to continue because it could force the concealed White Room assassin to act openly. 248
• Anticipated Hosen’s attempt to move Ayanokoji beyond the reach of surveillance and prepared decisive evidence in advance. 260 261
• Questioned whether Tsukishiro was deliberately withholding information about his growth from the White Room students rather than simply underestimating him. 249
• Recognized that ordinary island-exam competition was unlikely to eliminate him or Ayanokoji, making attacks intended to injure participants and force withdrawals a more plausible enemy strategy. 288
• Identified the clustered, supply-awarding Speed Race Challenges as a reliable means of obtaining necessities and anticipated that dwindling food and water would redirect other groups toward them. 288 299
• Inferred that Tsukishiro intended to let the first-years and White Room student attempt Ayanokoji’s expulsion before intervening personally if they failed. 300

Information Gathering and Leverage

Makoto uses surveillance, school authority, blackmail, and negotiated access to obtain information.

• Purchased a camera and directed Kamuro to secretly record Kushida. 18
• Blackmailed Kushida into acting as an informant within Class D while protecting the secret that gave him leverage over her. 22
• Used Student Council access and 50,000 personal points to obtain surveillance footage proving that Ryuen had inflicted injuries on his own classmates to support their accusation against Sudo. 45
• Identified all VIPs in the VIP Exam and sold information through formal, witnessed contracts. 78 84
• Used a concealed camera to preserve evidence of Hosen attacking Ayanokoji with a knife and threatening his life. 260 261
• Coordinated with Sakayanagi and Kanzaki to use footage from the Selection Project chess match to provoke public scrutiny of Tsukishiro’s interference before the school deleted the post. 249
• Retained evidence of Sudo and Ike’s involvement in Sotomura’s secret-filming incident for approximately half a year before releasing it at a strategically useful moment. 235 237
• Assigned Nanase to monitor first-year movements and report unusual activity to Ayanokoji. 274
• Obtained private reports from Mashima about Tsukishiro’s island activities and unusual rescue-boat arrangements. 299
• Concealed Utsunomiya’s presence before the island confrontation through a deliberately damaged watch that prevented his GPS signal from appearing on the opponents’ tablet. 311

Leadership and Organization

Makoto leads through planning, delegation, and the willingness to work alongside others.

• Led Class A’s island-exam efforts, assigning camp, reconnaissance, and base-occupation tasks. 57
• Worked on difficult physical tasks and conducted reconnaissance in heavy rain, earning his classmates’ trust. 80
• Built a volleyball team around the strongest available players instead of insisting on personal prominence; he served as setter while stronger teammates handled offense and defense. 104 106
• Entrusted Kanzaki with the main class group during the Mixed Training Camp while he led a mixed group to draw Nagumo’s attention away from classmates. 184
• Recruited capable representatives from multiple classes into the Student Council, including Katsuragi, Shiina, and Horikita, in preparation for future cross-grade threats. 101 109
• Served as Class A’s Command Tower during the Selection Project Special Exam, managing event selections and intervention privileges against Sakayanagi. 223 225
• Used his Student Council authority to impose a practical settlement on Hosen, pairing him with Ayanokoji while securing cooperation for Horikita’s class. 261
• Confronted Hirata’s withdrawal after the Additional Exam and urged him to accept responsibility, apologize, and resume helping his class. 219 221
• Divided second-year island-exam tasks among Kanzaki, Katsuragi, and Hirata, balancing movement destinations with academic, athletic, and other Challenges. 286 288 295
• Coordinated with Ayanokoji to protect vulnerable allies while preserving his own ability to compete against Sakayanagi. 275
• Merged his group with Ichinose’s and led the resulting seven-person formation to first place overall. 299 300 316
• Collaborated with Tsubaki to remove uninvolved first-years from the final conflict and arranged separate reinforcements for himself and Ayanokoji. 309 311

Political and Financial Maneuvering

Makoto turns personal points, Student Council authority, and class relationships into strategic assets.

• Sold signed “Shizuku” photographs to graduating third-years as a means of acquiring personal points within the school’s rules. 34 35 39
• Negotiated recurring payments for VIP information with Ryuen under a school-witnessed contract. 84
• Sought Sakayanagi Kōhei’s support to counter Nagumo’s advantage in the Student Council presidency contest. 124
• Spent 20 million personal points to recruit Katsuragi Kohei into Class A for both his ability and the class’s coming confrontation with Sakayanagi. 217
• Used the Selection Project’s manipulated final match to obtain Protection Points, reducing Tsukishiro’s ability to target him through the school’s rules. 226 227
• Instructed Kiriyama to announce Tsukishiro’s bounty through private channels while concealing Makoto’s involvement, allowing the bounty to function as bait for White Room students. 248
• Secretly supplied Ryuen with intelligence he could use to demand points from Nagumo, turning their shared interests into cooperation. 126
• Used pressure surrounding Tsukishiro and Yagami to build working alliances with Nanase, Tsubaki, and Utsunomiya. 300
• Paid Kiryūin to serve as a reinforcement during the island confrontation; she subsequently agreed to hold off Sima despite acknowledging that she could not defeat him. 311

Chess

Makoto is a capable chess player, though initially inferior to Sakayanagi in direct play. He has since trained under her guidance and uses chess as both a strategic discipline and a means of cooperation with her.

• Lost a chess game to Sakayanagi, who nevertheless recognized his restraint and strategic self-awareness. 40
• Took over the final chess match of the Selection Project after Ichinose’s loss and coordinated with Sakayanagi to pursue Protection Points. 226
• Continues practicing with Sakayanagi, who believes he has the talent to reach Candidate Master level. 230

Athletic Ability

Makoto began school with ordinary physical fitness but improved through sustained training.

• Developed noticeably improved conditioning and visible abdominal definition within several months. 103
• Won his Sports Festival 100-meter heat against Ayanokoji, who deliberately held back. 116
• Competed in the obstacle course, relay, scavenger hunt, and other nominated Sports Festival events. 113 118 122
• Won the final relay for Class A despite pressure from Nagumo and a dropped baton earlier in the race. 122
• After a year of training, reached a physical level near the school’s top-tier students, though he remains below exceptional figures such as Ayanokoji and Kouenji. 191 264
• Won the men’s Open-Water Swimming Challenge during the second-year island exam, earning 20 points for his group. 300
• Received an updated OAA Physical Ability rating of A (88) after the island exam. 316

Self-Defense Training

Makoto began practical combat training in preparation for future White Room students.

• Requested direct self-defense instruction from Ayanokoji during the Mixed Training Camp. 191
• Initially could not last three moves against Ayanokoji even with Ayanokoji controlling his strength; after repeated sparring, he could defend against several moves. 191
• Continued training with Ayanokoji and Kanzaki, often sustaining bruises from sparring. 198
• Received Ayanokoji’s assessment that he had “fairly good” talent and could have become one of the White Room’s best trainees. 191
• Endured extended high-intensity sparring with Ayanokoji and gained enough practical ability that Ayanokoji judged him capable of handling the expected first-year threats. 229
• Defeated Nanase Tsubasa by reading the limitations of her “Matsuo Eiichiro” persona, defending through her initial attacks, exhausting her full-force assault, and restraining her without serious injury. 264
• Defended against Yagami’s initial attacks during the island confrontation, relying on evasion, guarded counters, and retreat to avoid exposing openings while moving toward his concealed reinforcement. 311
• Has learned offensive techniques from Ayanokoji, but has practiced them less thoroughly than his defensive techniques. Utsunomiya’s support allowed him to attack more confidently without leaving himself isolated. 312
• Used a precise knee strike to Yagami’s outer thigh to interrupt an attempted throw of Utsunomiya, then tried to seize Yagami’s arm as part of their coordinated pincer attack. 312

Relationships

• Ichinose Honami — Class partner, trusted organizer, Student Council vice president, and later romantic partner. Makoto initially encouraged her Student Council application and relies on her to manage class and council work. 6 141 142 177 After they became a couple, he shared information about the White Room and Ayanokoji Atsuomi with her to eliminate gaps in their understanding. They later merged their island-exam groups and shared an overall victory. 204 299 316
• Ayanokoji Kiyotaka — Pragmatic ally. Their cooperation is based on non-conflicting interests: Makoto protects Class A’s position while Ayanokoji seeks a quiet school life. Ayanokoji later trains Makoto in self-defense, and they coordinate against White Room-related threats. 20 53 106 191 261 Their cooperation develops into greater mutual reliance: Ayanokoji accepts responsibility for protecting vulnerable allies during the island exam, while Makoto supplies intelligence, protective arrangements, and reinforcements. Makoto also deliberately encourages his emotional development and ordinary school life. 275 300 311 314
• Horikita Manabu — Mentor and predecessor as Student Council President. Manabu recognized Makoto’s potential, promoted him to vice president, and entrusted Horikita Suzune’s safety to him. 9 98 111 142 He later promised Makoto the 37 million private points saved by his class and provided his and Tachibana’s contact information upon graduation. 217 231
• Horikita Suzune — Rival-class student whom Makoto advises on leadership and Ayanokoji. She comes to view him as an examiner and model answer rather than a straightforward enemy. He later helps her use Hosen’s attack to secure cooperation for her class. 73 74 261 She adopts his practice of preparing recording equipment before dangerous negotiations and later travels in the island-exam group merged with Makoto’s. 257 299
• Sakayanagi Arisu — Strategic partner and occasional rival. They cooperated against Katsuragi and Nagumo, while Sakayanagi remains interested in testing Makoto’s abilities and background. She also mentors him in chess and works with him against Tsukishiro’s interference. 17 40 123 124 226 230 She challenges him to a proper contest in the second-year island exam, which his group ultimately wins. Afterward, she considers placing the trusted Kamuro at his side to strengthen her own position among the girls around him, while continuing to organize interclass opposition to Class A. 275 316 318 319
• Kushida Kikyo — Initially coerced informant; later Makoto’s openly acknowledged girlfriend. Their relationship developed from mutual leverage into intimacy and cooperation. 22 30 137 Her safety is one of his principal concerns before the second-year island exam. She also helps explain his protective arrangements for Ayanokoji to Sato. 275 300
• Sakura Airi — Makoto protected her from a stalker, assisted with her photography work, and supported her confidence after her identity as “Shizuku” became known. They later became lovers. 18 29 36 141 He also provided her with the best photography equipment available on campus. 163
• Karuizawa Kei — Makoto offered her protection through a deliberately ambiguous “more than friends, but not quite lovers” public identity, while pushing her to improve academically rather than exploit his reputation. 88 89
• Kanzaki Ryuji — Trusted Class A ally who assists with intelligence, leadership, and combat training. Kanzaki also supports Makoto’s information operations and becomes president of the school’s Judo Club. 57 78 198 232 He is a core teammate in the second-year island exam, handling movement destinations and joining Makoto in attempts to obtain valuable Challenge rewards. 286 288 295
• Katsuragi Kohei — Student Council ally valued for his ability, ideals, and reliability; Makoto later recruits him into Class A. 98 111 217 He joins Makoto’s island-exam group and takes responsibility for suitable academic Challenges. 286 288
• Hirata Yosuke — A student whose kindness and leadership potential Makoto recognizes, but whose guilt-driven behavior he challenges. Makoto helps him confront his withdrawal after the Additional Exam and encourages him to resume supporting his classmates. Hirata later becomes a member of Makoto’s island-exam group. 86 88 219 221 241 286
• Nagumo Miyabi — Major political rival. Makoto opposed Nagumo’s control over the second-years, defeated his team in volleyball, and ultimately succeeded him in the Student Council presidency struggle. 104 106 124 142
• Ryuen Kakeru — Hostile rival and transactional ally. Makoto has repeatedly used leverage against Ryuen while cooperating with him when their interests align. Ryuen’s defeat on the island leads him to recognize Makoto as an aggressive and formidable long-term opponent. 45 66 67 84 184 Their cooperation also includes a secret intelligence arrangement against Nagumo. 126
• Hoshinomiya Chie — Homeroom teacher and intelligence contact who paid Makoto to monitor Class D and later helped provide evidence against Ishizaki. 17 118
• Kiriyama Ikuto — Student Council vice president and political ally. Kiriyama privately warned Makoto about Tsukishiro’s bounty order and followed Makoto’s instructions to announce it without exposing their connection. 142 248
• Yagami Takuya — Hostile White Room student who approached Makoto as an emissary for Makoto’s older brother and later revealed his intent to expel Ayanokoji. Makoto treats him as a suspected assassin rather than a straightforward opponent. 232 233 247 By the island exam, Makoto openly identifies their conflict as one in which only one of them can remain at the school. He collaborates with Tsubaki and Utsunomiya against Yagami and ultimately fights him with Utsunomiya’s assistance. 293 309 311 312
• Amasawa Ichika — Ambiguous first-year observer who is interested in testing Makoto’s abilities. Although she warns him about the bounty, Makoto remains cautious of her hidden motives. 244 257 Makoto considers that she could be won over rather than treated only as an enemy. During the island confrontation, Tsukishiro and Sima confirm that she had not genuinely intended to complete her mission to expel Ayanokoji, consistent with Makoto’s assessment. 247 311
• Hosen Kazuomi — Violent first-year opponent whose attempt to attack Ayanokoji was anticipated and recorded by Makoto. Makoto forces Hosen into a team with Ayanokoji and obtains his cooperation through the threat of expulsion. 261
• Nanase Tsubasa — First-year Student Council member and combatant whom Makoto defeats in a controlled fight. He exposes the psychological restrictions of her revenge-driven “Matsuo” persona while demonstrating that she is not ready to challenge Ayanokoji. 242 264 He then offers her the opportunity to join his side. She subsequently monitors first-year activity for him and travels with Ayanokoji under his protective arrangements. 265 274 300
• Ishigami Kyo — First-year son of the Ishigami Group and Makoto’s chosen partner for the cross-grade special exam. Makoto considers him a politically safe and capable partner despite the uncertainty surrounding his motives. 245 247
• Tsubaki Sakurako — First-year collaborator against Yagami. After a casual encounter at the Anime Knowledge Quiz, she and Makoto establish cooperation based on their common enemy. Their collaboration helps remove uninvolved first-years from the final island confrontation. 286 293 300 309
• Utsunomiya Riku — First-year ally who consults Makoto about the plan involving Yagami and Ayanokoji. Makoto arranges for him to wait unseen in the forest during the final confrontation, and they fight Yagami together after Utsunomiya confronts him over Hatano’s expulsion. 300 311 312
• Kiryūin Fūka — Capable upperclasswoman and island-exam competitor whom Makoto hires as a reinforcement. She intervenes to support Ayanokoji against Tsukishiro and Sima despite the risk of disciplinary consequences. 280 288 311
• Mashima — Teacher who privately shares information about Tsukishiro’s activities during the island exam, including the additional rescue speedboat and daily patrols. 299
• Tsukishiro Tokinari — Acting chairman and institutional adversary who manipulates an exam in an attempt to expel Makoto. Makoto counters his schemes through Protection Points, information operations, alliances, and concealed reinforcements, and refuses his demand for cooperation during the island confrontation. 227 248 249 299 311
• Sato Maya — Ayanokoji’s romantic partner and a student Makoto seeks to protect from attacks aimed at Ayanokoji. Makoto regards her relationship with Ayanokoji as a particularly valuable influence on his emotional development. 265 274 275 314
• Kamuro Masumi — Covert operative initially recruited through Sakayanagi and pressured into assisting Makoto’s surveillance work. His observational reputation makes her wary of him; Sakayanagi later considers her the most trustworthy person to place at his side. 18 123 127 318

Story Role / Major Arcs

First-Term Class Advancement

Makoto establishes himself as a central force in his class by revealing school rules, organizing capable classmates, entering the Student Council, and helping his class overtake the original Class A. 1 6 9 21

Class D Operations

He targets Class D through Kushida, monitors Ayanokoji and Horikita, and repeatedly tests or pressures the class while avoiding a direct conflict with Ayanokoji. 17 20 22 53

His later interventions include helping Hirata accept responsibility after the Additional Exam and releasing retained evidence against Sudo and Ike during the controversy surrounding Kushida’s past. These actions combine personal guidance with calculated deterrence against future attacks. 219 221 235 237

Uninhabited Island Exam

Makoto leads Class A’s reconnaissance and resource strategy, secures a decisive victory, and earns widespread trust through both planning and physical effort. He also counters Ryuen’s leader-card trap and protects Class D from a larger penalty by becoming its replacement leader before withdrawing. 57 66 67 73 80

Student Council Succession

After becoming vice president, Makoto builds a multi-class Student Council network, confronts Nagumo’s influence, and succeeds Horikita Manabu as president. 98 109 124 142

White Room Preparations

Aware of the threat posed by incoming White Room students and the acting chairman’s hostility toward Ayanokoji, Makoto begins serious self-defense training with Ayanokoji and Kanzaki. 191 198

His training advances from limited defense against controlled sparring to extended high-intensity sessions, then to practical encounters with Nanase and Yagami. His defensive techniques remain more thoroughly practiced than his offensive repertoire. 229 264 311 312

Selection Project Special Exam

Makoto leads Class A against Sakayanagi’s Class B as Command Tower, recruits Katsuragi to strengthen his class, and counters Sakayanagi’s privileges through rule revision. The special exam exposes Tsukishiro’s willingness to manipulate school systems to target Makoto and Ayanokoji. 217 223 225 226 227

First-Year Bounty and White Room Countermeasures

When Tsukishiro places a 20-million-point bounty on Ayanokoji, Makoto turns the operation into bait for the White Room assassin. He investigates Yagami and other suspicious first-years while coordinating with Ayanokoji, Sakayanagi, and Kiriyama. 233 247 248 249

The countermeasures later expand into an alliance network involving Nanase, Tsubaki, and Utsunomiya. Makoto distinguishes between students drawn into the bounty and the White Room agents themselves, helping clear uninvolved first-years out of the eventual confrontation. 274 293 300 309

Hosen and Nanase Confrontations

Makoto prevents Hosen from using Horikita to lure Ayanokoji into an unrecorded attack, then uses the resulting evidence to impose conditions favorable to Horikita and Ayanokoji. He later defeats Nanase in combat, revealing the tangible results of his training. 261 264

Nanase’s defeat also becomes an opportunity to challenge the assumptions behind her revenge. Makoto offers her a choice between leaving school and joining his side, and she subsequently assists his efforts to protect Ayanokoji. 265 274 300

Second-Year Uninhabited Island Special Exam

Makoto accepts Sakayanagi’s challenge after Ayanokoji takes responsibility for protecting vulnerable allies. He uses the exam’s team-building resources, divides Challenges among capable teammates, and later merges with Ichinose’s group. Their formation rises to first place through coordinated movement and Challenge performance, including Makoto’s swimming victory. 275 280 286 288 299 300

The exam also requires him to manage threats beyond ordinary competition. He anticipates violent attempts to force withdrawals, receives warnings about attacks on other students, and obtains reports about Tsukishiro’s suspicious island preparations. 288 295 299

His group finishes first with 306 points, securing 225 class points for Class A after the first-place reward and Trial Card bonus are shared with Class C. The subsequent OAA update establishes him as the school’s first student with an A-grade overall evaluation. 316

Island Confrontation and Reinforcements

After reducing the involvement of ordinary first-years, Makoto directly refuses Tsukishiro’s demand for cooperation. He withstands Yagami’s initial assault while drawing the fight toward Utsunomiya’s concealed position, then coordinates attacks with him. Kiryūin, separately recruited by Makoto, supports Ayanokoji by delaying Sima. 309 311 312

The confrontation highlights the development of Makoto and Ayanokoji’s cooperation beyond their original non-aggression agreement. Ayanokoji credits Makoto with allowing him to avoid unwanted class competition and enjoy ordinary school life, while Makoto sees emotional development as another way to counter the influence of Ayanokoji Atsuomi. 311 314

Renewed Interclass Rivalry

Following Makoto’s island victory, Sakayanagi continues preparing opposition to Class A. She argues that coordinated pressure from the other three classes could overcome Class A’s athletic depth and arranges to discuss cooperation with Horikita. 316 319
