Kakeru Ryūen (
Kakeru is a young man of average height with long magenta hair. In addition, he has a slim and muscular physique. His sharp eyes strike fear onto anyone he met.
In the light novel, he wears the uniform of the school. However, in the anime, his dressing consists of a standard red jacket and a unbuttoned black shirt underneath with no tie.
Kakeru is a blameworthy and delinquent person who likes causing trouble for others, this was seen when he and his gang caused trouble for Ken Sudō. He also possesses a sadistic side as shown when he looked as if he was going to attack the helpless Ken after his men held him down only to instead flick him on the head laughing at his fear. He is very ruthless as he took a glass bottle and hit one of his followers on the head with it, showing no remorse after the act. This shows he is willing to use followers for any goal as sees fit to achieve his purpose till the end without a second thought. He is also shown to be very insubordinate and disrespectful to certain characters as shown when he spoke with Suzune Horikita and Mio Ibuki even having Albert Yamada throw the latter down after telling her to come to his room.
Despite his intimidating and dangerous appearance, Kakeru is sharp in his own way of thinking as he was quick to cover his tracks by telling Honami Ichinose when she witnessed the event that it was self-defense. He would come up with many unexpected strategies, this was seen when he and one of his followers attack an injured follower who failed in his task to get frame Ken Sudō for assault and get him expelled. He also chose not to pick a fight with class 1-A while in the presence of Manabu Horikita, the Student Council president.
In the light novels, he showed great fear of Kiyotaka Ayanokōji after the latter viciously attacked him. This event caused him to note on how shaken he was. Also, he is embarrassed by Rokusuke Kōenji for nicknaming him which caused Arisu to making fun of him by repeating his embarrassing nickname.
Kakeru is notorious delinquent who has gathered many followers and as the representative of his class, he is the leader of his class ruling them not by loyalty but fear.
In spite of his violent mindset, Kakeru is shown to be very intelligent as he forged an alliance with Kōhei Katsuragi to aid him in the survival test. He also planted spies in camps of classes 1-B and 1-D in order to learn the identities of the leaders to gather points for his own. He did this in a way to garner more points for his class due to a contract with Kōhei and his plan would been successful had he not been outsmarted by Kiyotaka.
He is shown to be very strong as he was able to intimidate Daichi Ishizaki, who was a delinquent in middle school that picked fights and was able to scare Ken another delinquent. He also was seen physical harming Mio, and overpowered her pretty easily, despite her knowledge of several martial arts skills, while he didn't even flinch when she tried to kick him.
During his brawl with Kiyotaka at Volume 7, Kakeru simulated techniques and moves from various martial styles. The former noted that the latter must have self-taught himself to have mastery in his combative skills. Despite his prowess, he was shown to be no match for Kiyotaka's power who easily threw him to the ground and violently attacked him.
- He shares the same birthday with Kiyotaka Ayanokōji.
