• Sharp, ferocious eyes and a perpetually aggressive expression. 40 98

Personality

Ryuen is forceful, confrontational, and highly competitive. He treats fear as the foundation of leadership, having forcibly unified Class C through violence and an unyielding will. 39 He enjoys provoking opponents publicly, particularly Akiyama Shin, and routinely uses insults, threats, and humiliation to destabilize other classes. 40 79

Despite his brutality, Ryuen is neither careless nor unintelligent. He possesses sharp instincts, quickly notices deception, and is willing to form alliances or gamble on uncertain information when it can create an advantage. 77 92 162 However, his impatience and obsession with defeating Akiyama repeatedly lead him into premature conclusions and costly mistakes. 85 92 95

After Akiyama defeats him, Ryuen remains fixated on surpassing him rather than withdrawing. He explicitly asks Akiyama to use his full strength in their future competition. 132

Abilities & Skills

Intimidation and Coercion

Ryuen controls subordinates and opponents through threats, physical pressure, and the expectation of violence.

• Established control over Class C through violence and fear. 39
• Uses Ishizaki Daichi and Yamada Albert as enforcers during confrontations and extortion attempts. 39 63
• Intended to isolate Akiyama on the rooftop, confiscate his Terminal, prevent recordings, and force an unfair agreement over Sudo Ken's case. 63
• Lured Horikita Suzune into an abandoned corridor using forged handwriting and attempted to seize Class D's Sports Festival forms. 106
• His reliance on fear becomes a weakness when Class C students choose self-preservation over loyalty. 68

Strategic Manipulation

Ryuen exploits rules, money, internal divisions, and false appearances to weaken rivals.

• Tried to extort Akiyama's Personal Points by exploiting Sudo Ken's violence case. 63
• Planted Ibuki Mio in Class D and Kaneda Satoru in Class A during the Uninhabited Island Exam to gather leader intelligence. 79 81
• Formed a secret arrangement with Katsuragi Kohei: Class C supplied Class B with resources in exchange for a three-million-Point consulting payment. 77
• Offered Yamauchi Haruki one million Personal Points to steal Class D's Sports Festival entry list and betray Akiyama. 99
• Used forged writing connected to Horikita Manabu to draw Suzune into his trap. 106

Deduction and Psychological Warfare

Ryuen has strong observational instincts and actively probes others for hidden motives or identities.

• Immediately recognized that Akiyama's apparent Uninhabited Island leader arrangement was a performance meant to mislead observers. 77
• Grew cautious of Class D's layered misdirection during the VIP Exam after being deceived by the earlier leader smokescreen. 85
• Incorrectly identified Koenji Rokusuke as the Earth Group VIP, but later discovered the exam's gojuon-order pattern and correctly identified VIPs in two other groups. 87 92
• Approached Ayanokoji directly during the Beauty and Ugliness Game, treating their partnership as a gamble on Ayanokoji's concealed identity. 162
• Cooperated with Sakayanagi Arisu to coordinate voting and suppress Akiyama's side in the same exam. 163

Physical Resilience

Ryuen favors force, though his most decisive physical confrontation ends in defeat.

• Was beaten alongside Ishizaki and Albert by Akiyama after confronting Horikita. 107
• Required hospitalization following the assault. 110
• Akiyama later considers Ryuen tougher than Hosen Kazuomi at taking hits. 183

Relationships

• Akiyama Shin — Primary rival. Ryuen repeatedly provokes, schemes against, and challenges Akiyama, but suffers several strategic defeats before being physically defeated by him. 40 92 107 132
• Ishizaki Daichi — Loyal subordinate and frequent enforcer. Ishizaki gathers intelligence, accompanies Ryuen in confrontations, and follows his orders without question. 39 63 107
• Yamada Albert — Loyal subordinate and physical enforcer who commonly accompanies Ryuen and Ishizaki. 39 75 107
• Ibuki Mio — Class C operative sent to infiltrate Class D during the Uninhabited Island Exam; her growing conflict with Ryuen's methods undermines her mission. 79 81
• Katsuragi Kohei — Temporary Uninhabited Island Exam partner. Their secret resource-and-Personal-Point arrangement supports Ryuen's leader-identification strategy. 77 79
• Sakayanagi Arisu — Initially rejects Ryuen's proposal to cooperate against Akiyama, but later agrees to coordinate with him during the Beauty and Ugliness Game. 98 163
• Yamauchi Haruki — Recruited by Ryuen with a one-million-Point offer to leak Class D's Sports Festival information. 99 103
• Horikita Suzune — Target of Ryuen's traps and intimidation. He lures her into an old school building corridor before Akiyama intervenes. 106 107
• Kiyotaka Ayanokoji — Ryuen regards Ayanokoji as suspiciously capable and forms a contract partnership with him to probe his true identity. 162

Story Role / Major Arcs

Library Provocation

Ryuen makes his major entrance by leading Ishizaki and Albert into a Class B and Class D study session. He insults Class D as “defective goods” and seeks to provoke its leaders, but Akiyama's response prevents the confrontation from escalating on Ryuen's terms. 39 40 41

Sudo Ken Incident

Seeing Akiyama's large Point balance as an opportunity, Ryuen attempts to use Sudo's violence case to extort Class D. Akiyama counters by turning Class C students Komiya Togo and Kondo Reon against him; their testimony contributes to Ryuen's suspension and Class C's loss of 50 Class Points. 60 63 68 70

Uninhabited Island Exam

Ryuen allies with Katsuragi, spends Class C's S Points on supplies, and deploys Ibuki and Kaneda as infiltrators. Although he identifies Ayanokoji as a potential leader, Class D's misdirection and eventual leader switch disrupt his plan. 77 79 81

VIP Exam

Believing he has finally seen through Akiyama's deception, Ryuen prematurely identifies Koenji as the Earth Group VIP. The guess is wrong, awarding Class D 50 Class Points while deducting 50 from Class C. Ryuen later discovers the planetary gojuon-order rule, but too late to fully capitalize on it. 87 92

Sports Festival Conflict

Ryuen attempts to recruit Sakayanagi and succeeds in buying Yamauchi's betrayal. He then traps Horikita to steal Class D's application forms, only for Akiyama to arrive and defeat Ryuen, Ishizaki, and Albert. Ryuen is hospitalized and misses the Sports Festival, while Class C ultimately loses 200 Class Points. 98 99 106 107 110 114

Later Rivalry

At the Southern Alps training camp, Ryuen openly demands that Akiyama face him at full strength. Akiyama refuses to use physical force, stating that he is afraid he would beat Ryuen to death. 132

During the later Beauty and Ugliness Game, Ryuen continues his identity-based psychological warfare, partnering with Ayanokoji and coordinating with Sakayanagi against Akiyama. 162 163
