Background / History

Ryuen established himself as Class C's leader shortly after enrollment through intimidation and violence. He assaulted classmates who questioned him, demanded obedience, and repeatedly fought resistance from Ishizaki and Albert. Albert could overpower him physically, but Ryuen remained defiant even after being beaten. At the same time, he actively gathered intelligence on the school and rival classes. 25

His early strategy centered on testing institutional limits: he targeted Sudo to gauge both the school's response to trouble and the strength of Class D's leadership, while seeking opportunities to extract Private Points. 44

During the Uninhabited Island Exam, Ryuen maintained the appearance of a carefree beach camp while limiting major expenditures and operating a scheme involving Ibuki Mio. After the plan failed, he returned Horikita Suzune's key card and proposed that their classes stop pursuing each other's leaders so they could focus on other opponents. 72 87 Despite his dictatorship, he is stated to seek Class C's promotion to Class A alongside all of its members. 87

Appearance

Ryuen is a red-haired boy with shoulder-length hair and an imposing, confrontational presence. He is frequently described with a sharp, predatory gaze. 25 215

• Shoulder-length red hair. 25
• His right eye was swollen and purple during his first encounter with Yuyuki. 25
• Wore sunglasses and swim trunks while overseeing Class C's island camp. 72
• His facial injuries became conspicuous after Yuyuki beat him during the Mixed Camp. 217

Personality

Ryuen is domineering, confrontational, and openly contemptuous of rules, social niceties, and opponents he considers weak. He treats fear as a tool of leadership, often provoking people into emotional mistakes or forcing them into choices that favor him. 25 145 309

He is also highly persistent. Even after being physically outmatched by Albert, humiliated by Yuyuki during the Sports Festival, and severely beaten at the Mixed Camp, he continues to threaten retaliation and search for advantages. 25 143 217

Beneath his cruelty, Ryuen is protective of the people he considers his own. His leadership shields followers such as Ishizaki from concentrated criticism, though his overprotection also prevents many classmates from developing beyond their existing academic and physical abilities. 298 304

Abilities & Skills

Strategic Planning and Rule Exploitation

Ryuen studies incentives, loopholes, and institutional responses rather than relying only on direct confrontation.

• Tested school authority and rival-class leadership by targeting Sudo. 44
• Used an extravagant-looking island camp as misdirection while restricting costly supplies. 72

Psychological Warfare and Manipulation

• Used Yajima's injury to pressure Horikita Suzune into either admitting guilt or paying compensation. 145
• Spread information about Ichinose's large Private Point reserve, placing her class under suspicion. 295 296

Leadership

Ryuen can impose unity through fear and decisive action, but his poor reputation limits genuine cooperation.

• Finished first in his class's compliment-vote results after securing outside votes and organizing support from his followers. 324

Combat and Mental Resilience

Ryuen fights with aggressive, improvised tactics rather than refined technique. His greatest strength is his refusal to submit.

• Uses sudden kicks, headbutts, thrown objects, and other street-fighting tactics. 25 109 215
• Is physically weaker than Albert and was judged to be only roughly comparable to Horikita Suzune in combat ability. 25 109

• Ichinose Honami — Target of a Private Point rumor and attempted manipulation; Ryuen approached her hoping to exploit her class's financial situation. 295 296

Story Role / Major Arcs

Early Class C Domination

Ryuen takes control of Class C through violence while independently collecting intelligence on the school and its class system. His attack on Sudo is intended to test Class D's leadership and the boundaries of school authority. 25 44

Uninhabited Island Exam

Ryuen coordinates Class C's deceptive beach-camp strategy and uses Ibuki as part of his operation against Class D. When the circumstances shift against him, he returns Horikita's key card and proposes a temporary truce. 71 72 87

Favored Student Exam and Sports Festival

He attempts to split Class B and D by proposing cooperation against Class A, then relies on dirty tactics and psychological pressure during the Sports Festival. His schemes include sabotaging Sudo's team, using hair wax to make his headscarf difficult to seize, and framing Horikita through Yajima's injury. 108 140 143 145

Mixed Camp

Ryuen tries to build a fifteen-person cross-class group, recruits Katsuragi, and later breaks an agreement over group membership. His strategy fails when senior students refuse to surrender leadership. After confronting Yuyuki with a group of followers, he is decisively beaten but refuses to back down. 204 206 214 215 217

Dropout Vote Crisis

Facing possible expulsion, Ryuen searches for Private Points and compliment votes, negotiates with Katsuragi and Horikita, and publicly mistreats Ishizaki while retaining his followers' loyalty. Humiliated by Nagumo, he accepts a ten-million-point loan and an obligation to fulfill a future request. 298 309 311 320 321

Ryuen ultimately avoids expulsion by securing extra compliment votes and concentrating his faction's Criticism Votes on Tokito Yuya, who is expelled instead. 324
