Arisu Sakayanagi/Relationships

Arisu is one of the most intellectual students at Advanced Nurturing High School and is highly respected for her status by teachers and students alike. Her reputation of being the leader of Class 2-A is widely known, creating an aura of both fear and admiration when anyone is in her presence. For the respectively leaders of the other classes, she acts as the benchmark and final goal for all of them to overcome. Additionally, she is commonly used as the encapsulation of a paragon student and is a common topic of comparison especially for the students at the top.

Manabu Horikita
Manabu Horikita, the previous Student Council president at that time who has extremely high standards, praised her grades in the recent midterms. This was notable, as the only other person he had ever been seen complimenting was Kiyotaka Ayanokōji, who is extremely intelligent and skilled in manipulating his academic ability in his own right.

He even praised her phenomenal holistic management of her class, such as being able to stand out from the rest of the classes in terms of class points despite only having a handful of weeks to establish her control, and personally invited her for a chat to commend her achievements.

Masayoshi Hashimoto
During Vol 7, Arisu was saved by Masayoshi Hashimoto after Ryūen violently assailed her for repeating Rokusuke's embarrassing nickname for him. (e.g. "Dragon Boy") This shows that he is willing and capable of putting himself in troublesome circumstances for the sake of his leader, not condoning any harmful actions that is directed at her.

Hashimoto obediently follows all of Arisu's instructions and often calls her "princess" showing his love, admiration and respect towards her. Kiyotaka feels that Hashimoto is one of the most stalwart and significant ally of Arisu, admitting that it won’t be easy to take him down as he acts as one of the limbs supporting Arisu.

Kakeru Ryūen
She appears to be familiar and aware of him when school first started. When she and Kōhei were checking out the scores of each class, they saw Class C was catching up and she knew it was due to 'his' efforts calling him persistent. They met face to face in the courtyard where they had a chance to converse. Kakeru remarked on how it looked as if she established her rule in the school very quickly. He swore to her that he will take down all the classes including hers so that he could be the one who will rule the school. She found his declaration interesting and readily accepted the challenge. Unlike his usual stoic attitude, he takes her as a very serious threat and was impressed of how in the span of days, a year 1 student like her could already have so much control over the school and the highly reputable Class 1-A filled with the cream of the crop students, admitting that it isn’t a easy feat.

Kiyotaka Ayanokōji
No direct interaction has been seen yet between the two in the anime.

Suzune Horikita
During Ryūen's confrontation of Rokusuke Kōenji, Arisu immediately stated that there is a possibility that "X" doesn't exist and that Suzune Horikita should be at the watchlist given that she's the one who manipulated the settings during the special summer exam at the deserted island. She knew that Kiyotaka was using Suzune as something akin to a pawn and admitted defeat when he was able to train his 'apprentice' to defeat hers during the chess match.
