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.

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 being saved by Masayoshi Hashimoto after Ryūen violently assailed her for repeating Rokusuke's embarrassing nickname for him (e.g. "Dragon Boy")

Hashimoto obediently follows all of Arisu's instructions and often calls her "princess" showing his love and respect towards her.

Kakeru Ryūen
She appears familiar with him as 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 meet face to face in the courtyard where they spoke with Kakeru remarking 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 rule the school as she found his declaration interesting and accepted the challenge. Unlike his usual attitude, he takes her as a threat very seriously as was impressed in the span of days, a year 1 student like her could already have so much control over the school and highly reputable Class 1-A filled with the cream of the crop students.

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.
