Ryuen Kakeru

Biodata

Background

Ryuen takes control of Class C on the first day of school through violence and intimidation. He covers the classroom cameras, but Asakusa Toru records what happens and confronts him. Ryuen pays Asakusa two million Private Points for information about the school’s Class Points, exams and class hierarchy 5 6 7.

He continues forcing holdouts to submit, including Ishizaki Daichi and Yamada Albert. With support from homeroom teacher Sakagami Kazuma, Ryuen has secured control of the class by mid-April 13 14 115. His longer-term ambition is to accumulate eight hundred million Private Points and move the entire class into Class A 308.

Appearance

Ryuen has long, dark-crimson hair described as gloomy 120.

Personality

Ryuen is tenacious and willing to use intimidation, provocation and traps rather than rely on a fair fight. He does not consider himself the strongest student, but believes he can outlast his opponents 13 14 116. He also resents the influence he believes Sakayanagi Arisu gains from her connection to the school chairman, even while using underhanded methods himself 120 177.

As a leader, he weighs the cost of a tactic against its benefit to Class C. He avoids a reckless confrontation that would waste Class Points, seeks advice from Shiina Hiyori, and later keeps a partnership rather than betray it for an insufficient gain 116 233.

Relationships
