Ryuen

Kakeru is a young man of average height with shoulder-length magenta hair that is styled on either side, and sharp magenta coloured eyes that strikes fear and trepidation onto anyone he comes into contact with. In addition, he has a slim and muscular physique. His attire consists of a standard red jacket and an unbuttoned black shirt underneath without a tie.

Kakeru is a blameworthy and reprehensible person who loves causing trouble for others as seen when he and his gang purposefully caused conflict with Ken Sudō and wanted to expel him.

He also possesses a sadistic nature, as shown when he looked as if he was going to attack the vulnerable Ken after his men held him down only to instead flick him on the head while laughing at his fear. He was 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 and many other actions shows that he is willing to use followers for any goal as he sees fit to achieve his purpose of controlling the school and enjoying himself. He is also shown to be 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 acute in his own way of thinking, as he was quick to cover his tracks by telling Honami Ichinose even when she witnessed the event by declared that it was out of self-defence. He would come up with many unexpected strategies such as when he and one of his followers attacked another injured follower who failed in his task to 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 and knows that he isn’t capable at that moment to take on Arisu Sakayanagi.

In spite of his regular violent actions and tenancies, Kakeru is shown to be someone who is very intelligent as he successfully persuaded and forged an alliance with Kōhei Katsuragi to aid him in the survival test. He also planted spies in the respective camps of classes 1-B and 1-D in order to learn the identities of the leaders to gather points for his own class without the respective class leaders finding out. He did this in a way to garner more points, due to the contract with Kōhei. His plan was able to outplay Suzune Horikita and would have been successful had he not been outsmarted by Kiyotaka Ayanokōji intervening. Eventually, he was able to convince Kohei to join his class and leave Class A by appealing to his complicated history with Arisu Sakayanagi. It is said that his leadership and presence in his class is the only reason they are able to remain competitive with the other classes and without him, his class would have would be in constant pandemonium.

Kakeru is shown to be very strong, as he was able to intimidate and have complete dominion over Daichi Ishizaki, who was a notorious delinquent in middle school who has seen his fair share of fights. He is also not afraid to pick fights and was able to terrify Ken, another delinquent. He is also seen being capable of physically harming Mio Ibuki, and overpowering her relatively easily, despite her knowledge of several martial arts skills and being stated to be the strongest second year girl. For instance, he didn't even flinch when she attempted to kick him.

During his brawl with Kiyotaka Ayanokōji in Volume 7, Kakeru simulated techniques and moves mixed 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.[2] Kiyotaka remarked that he shouldn’t have been able to gain the loyalty of someone like Albert Yamada through normal means, hinting his manipulative talents while also implying that he is not as physically capable as Albert.

He is also not above losing as long as it comes with a price, such as when he agreed to lose in an exam after Sakayanagi agreed that she owed him a debt if he acquiesce her request, after knowing of her desire to protect Kiyotaka. He was also able to stall Kazuomi Hōsen for some time, which was stated to be someone on the tier of Albert.

His Henchmen include: Daichi Ishizaki: One of Ryūen's main enforcers, a muscular and hot-headed student who often acts on impulse. Despite his lack of intelligence, he is fiercely loyal to Ryūen, viewing him as a true leader. Ishizaki is often the one to carry out Ryūen's more physically confrontational orders.

Mio Ibuki: A cunning and athletic student who is initially tasked with spying on other classes. Ibuki is a highly skilled fighter, but she is also very stubborn and prideful. She has a complicated relationship with Ryūen, often clashing with him despite being part of his group. Her loyalty to Ryūen is not based on fear, but rather on her own goals and a shared understanding of their cutthroat world.

Albert Yamada: One of Ryūen's less prominent but still loyal followers. He is often seen alongside Ishizaki and is another one of Ryūen's enforcers, carrying out his orders with little to no hesitation. He is a more subdued character compared to the others but is just as dedicated to Ryūen's cause.

The gang's dynamic is centered on Ryūen's absolute control. While they may not always agree with his methods, the members of the gang follow his orders out of a combination of fear, respect for his cunning, and the belief that his leadership is the only way for their class to succeed. They are not a group built on camaraderie, but on a shared understanding of power and a desire to climb the school's social hierarchy, no matter the means. Their influence is felt throughout the school, as they are a constant threat to other classes and a major obstacle for the protagonist, Kiyotaka Ayanokōji.
