Background

Chen Ze was a university student from Earth who transmigrated into the body of Ryuuen Kakeru as an infant. Over the following sixteen years, he trained, founded businesses, and pursued relationships in preparation for entering Advanced Nurturing High School. The original Ryuuen's ambition to become an entrepreneur had already been fulfilled through Chen Ze's actions; his new goal was to bring Class C to Class A. 1

Upon entering the school, Ryuuen immediately identified the value of both strength and information. He planned to unify Class C through coercion, considering violence the fastest means of making weaker students obey while recruiting the strongest students as useful assets. 2

Ryuuen seized control of Class C by ordering every student to surrender half of their monthly Points to Shiina Hiyori, then challenged any opponent to confront him on the rooftop. He defeated Yamada, Ibuki, and nearly all of Class C's boys, securing his position through overwhelming force. 3 5

His rule later became more structured: Hiyori held the class's pooled Points and handled many internal affairs, serving as both a trusted administrator and a restraint on Ryuuen's authority. Under his leadership, the class eventually rose to Class A. 7 197

Appearance

Ryuuen is a blond-haired student whose appearance was refreshed before enrollment when he adopted a wolf-tail hairstyle inspired by Azuma Michinaga's look from Kamen Rider Geats. 1

• Bright yellow hair from infancy. 1
• Wears his hair in a distinctive wolf-tail style. 1
• Is three centimeters shorter than Ayanokoji Kiyotaka. 30
• Maintains a heavily trained physique through combat practice, running, and physical conditioning. 5 69

Personality

Ryuuen is arrogant, confrontational, and highly confident in his own judgment. He treats hierarchy as something to be imposed rather than negotiated, frequently provoking opponents to test their limits or force them into revealing their intentions. 2 36

He is also calculating and commercially minded. Ryuuen turns information, Points, favors, employment prospects, and personal weaknesses into bargaining tools, often preferring arrangements in which every participant is indebted to him. 5 39 151 485

Despite his ruthless methods, Ryuuen is not uniformly cruel. He can be protective of people he values, entrust responsibility to capable allies, assist injured students, and intervene against threats to those within his sphere. 7 70 234 434

Ryuuen enjoys literature and shares an interest in Gustave Le Bon's The Crowd with Hiyori. He also approaches competition as entertainment when the stakes do not directly threaten his larger goals. 2 7 270
