Background / History

Ryuen emerges as Class C’s dominant figure shortly after Kitahara Seiichi becomes known across the first year. With limited information available, he resolves to test Kitahara’s strength. 8

He establishes control over Class C through violence and fear, treating his classmates as subordinates expected to carry out his orders. Horikita Manabu identifies this reliance on violence as a weakness against opponents such as Ayanokoji. 28

Personality

Ryuen is aggressive, provocative, and intensely confident in his ability to dominate the school. He repeatedly declares that he will crush every other class and become the school’s sole “king.” 37

He values results over fairness, morality, or the well-being of his own classmates. He considers private points a means to obtain anything—including positions in clubs—and is willing to use deception, intimidation, and expendable pawns to gain an advantage. 53 66 109

His confidence can become a liability. He reacts visibly to being deceived or outmaneuvered, particularly by Class B during the Uninhabited Island Exam and by Kitahara during later negotiations. 66 68 97

Abilities & Skills

Strategic Manipulation

Ryuen designs schemes that exploit school rules, class rivalries, and students’ personal weaknesses.

• Planned Class C’s operation against Sudo, using Ishizaki’s group and a staged narrative to pressure Class D. 27 29 33
• Developed the “Zero-Point Strategy,” exhausting Class C’s resources while using hidden members and intelligence gathering to pursue a final-day advantage. 53 61
• Recruited Hashimoto from Class A to identify Class A’s leader while maintaining a separate agreement with Katsuragi. 53
• Uses provocation to push opponents into penalties, notably goading Sudo during the Sports Festival. 106 109

Coercion and Intimidation

Ryuen maintains authority by threatening, humiliating, and physically abusing subordinates.

• Punished a wounded subordinate for fearing that witnesses had seen Class C’s actions. 27
• Treated Kaneda as a disposable operative during the island exam, responding with contempt after Class B deceived them with a fake Key Card. 66
• Dismisses potential dissent within Class C, claiming that anyone who disobeys him will face consequences. 78

Information Networks and Deal-Making

Ryuen obtains intelligence through contacts, temporary alliances, and transactional agreements.

• Maintains Class C contacts who report on Class D’s circumstances. 18
• Worked with both Katsuragi and Hashimoto during the Uninhabited Island Exam despite their opposing Class A factions. 51 53
• Accepted Kitahara’s VIP Exam proposal to make Class C a spectator in exchange for 10 million private points. 80 83

Limitations

• His plans depend heavily on subordinates following instructions; he blames failures on their incompetence rather than reassessing his own strategy. 37 53
• He was deceived by Class B’s fake Key Card operation and finished the Uninhabited Island Exam in fourth place with zero points. 66 68
• His fixation on finding the person supporting Horikita leads him to suspect Ayanokoji, whom he ultimately fails to outplay during the island exam. 65 69

Relationships

• Kitahara Seiichi — Rival and occasional transactional partner. They wagered control of the next special exam during the Uninhabited Island Exam; Ryuen later followed Kitahara’s VIP Exam arrangement for profit, mockingly calling him “Master.” 67 76 80 82 83
• Ayanokoji Kiyotaka — Suspected hidden mastermind behind Class D. Ryuen identifies him as a possible leader during the island exam and vows to expose him in a later exam. 40 65 85
• Sudo Ken — Target of Class C’s schemes and Ryuen’s provocations. Ryuen exploits Sudo’s temper and love of basketball to force penalties and disqualification. 27 106 109
• Ibuki Mio — Class C member who openly challenges Ryuen’s decisions, especially his Zero-Point Strategy, but eventually accepts his reasoning. 53 65
• Kaneda Satoru — Subordinate used as an informant and thief during the island exam; Ryuen shows little concern for him after the Key Card scheme fails. 59 65 66
• Sakayanagi Arisu — Rival class leader. Ryuen declares his intention to crush Class A after Class D and Class B, while Sakayanagi dismisses his provocations and calls him “Dragon Boy.” 37 103
• Katsuragi Kohei — Temporary ally and rival. Ryuen cooperates with him during the island exam while separately seeking intelligence against Class A through Hashimoto. 51 53

Story Role / Major Arcs

Class C’s Operation Against Sudo

Ryuen directs Class C’s attempt to frame Sudo and pressure Class D. After the plan collapses and the complaint is withdrawn, he punishes the subordinates involved and begins looking for the person who disrupted his operation. 27 36 37

Uninhabited Island Exam

Ryuen spends Class C’s private points as part of his Zero-Point Strategy, uses Kaneda to infiltrate Class B, and attempts to steal Ichinose’s Key Card. Class B deceives him with Hoshinomiya’s card, and Class C finishes fourth with zero points. 53 61 66 68

Before the results, he wagers Kitahara that Class C will defeat Class D. His loss obligates him to yield leadership of the next special exam under their agreement. 67 76

VIP Exam

Ryuen agrees to Kitahara’s Outcome 1 plan, allowing Class C to act as a spectator for a promised payment of 10 million points. His cooperation helps isolate Class A and pressure Katsuragi. 80 82 83

Sports Festival

Ryuen clashes with Class B and Kitahara while pursuing undisclosed schemes during the festival. He later provokes Sudo into attacking him after arranging for Class C students to purchase basketball starting positions, resulting in Sudo’s disqualification and a 200-point deduction from the Red Team. 104 106 109
