Kakeru Ryuuen is the class representative of Class 1-C and is known for being an infamous delinquent. He does not lead his class by trust, but rather by fear. He has a group of henchmen who do his dirty work, which contributes to his fearsome reputation.
In the light novels, he showed great fear of Kiyotaka Ayanokouji after the latter viciously attacked him without an ounce of compunction. This incident caused him to note how shaken he was from it and how it was a first for him. Also, he is embarrassed by Rokusuke Kouenji for nicknaming him "Dragon-Boy", which caused Arisu Sakayanagi to making fun of him by repeating it.
Despite his ruthless nature he does seem to care for his class. For instance, he approached Hiyori Shiina as he was worried about her for always being alone. He also treats her as an indispensable ally in their class and is one of the people he truly respects.
