Background / History

Before enrollment, Ryuen was identified by Sima Zhenglong as the only leader in their year willing to pursue an unprecedented large-scale private-point strategy. On the bus to Advanced Nurturing High School, the two agreed to work together toward a 760 million-point objective, prioritizing special-exam earnings, point exchanges, and preserving Class C's initial class points. Ryuen accepted responsibility for conquering and leading the class while Zhenglong handled related infrastructure and information sales 3.

At the start of the school year, Ryuen seized Class C's leadership. He demanded 80,000 personal points from every classmate, used Sakagami's responses to expose the hidden class-point system, and established discipline as the class's immediate priority. Sakagami's visible approval strengthened Ryuen's position, while Zhenglong and Hiyori paying first encouraged the rest of the class to comply 5.

Ryuen framed his leadership as a collective wealth-building project: if he could not achieve the 780 million-point target, he promised to distribute the accumulated points among the class proportionally, retaining only a service fee. His intimidation and efficiency rapidly unified Class C, including Ishizaki and later Albert 6 7.

Personality

Ryuen is domineering, confrontational, and openly enjoys forcing others into disadvantageous positions. He claims the title of Class C's “monarch,” treats hesitation as proof that others are unfit to lead, and relies on intimidation to establish obedience 5.

Despite his delinquent persona, he is highly pragmatic in negotiations and long-term strategy. He can separate business from personal behavior, treating paying partners seriously and making Class C's services available to whichever class meets his price 37. He also recognizes the value of class unity, intelligence networks, preparation, and preserving resources rather than pursuing indiscriminate destruction 3 10 36.

Ryuen has a cruel and mischievous streak. He takes pleasure in Sakayanagi's disappointment, spits in Zhenglong's food as a petty provocation, and proposes humiliating psychological tactics against Sudo and Class D 17 23 46. However, he is capable of close strategic cooperation with Zhenglong, whose plans he quickly understands and develops further 3 18 19.
