Arisu is one of the most intellectual students at Advanced Nurturing High School and is highly respected for her status.

Family Edit

School Chairman Sakayanagi Edit

Arisu has a close tight-knit relationship with her father Mr Sakayanagi, who also serves as the chairman of the high school she is in. However, this connection wasn't the reason why she got into the A-Class as it was revealed that under fair circumstances, Arisu has the capability to have mastery over most of the points of assessments — which, indeed, deserves to be among the ranks of the best students of her generation.

Class A Edit

Kōhei Katsuragi Edit

LN Vol 05-00

Arisu and Kōhei Katsuragi.

She and Kōhei are often seen together and as representatives of Class A, they get along very well. It appears Arisu is the leader in their standing as Kōhei is shown addressing her when asking for her thoughts on the matters with other classes. Despite their partnership, it is mentioned by Honami Ichinose that the two have disagreements on how to properly run things.

It seems she doesn't mind doing things behind his back or discrediting as she had Masayoshi Hashimoto make a deal with Kakeru Ryūen after discovering Kōhei had made his own agreement. Her actions led to him being criticized for his poor judgment from the class, this shows she has no real concern for his reputation.

In Volume 7.5 Kamuro searches for Sakayanagi and found her having a chat with Ayanokoji at the mall, upon meeting with them Sakayanagi asked Kamuro about her thoughts about Ichinose. Sakayanagi told Kamuro that she have the same problem with Ichinose, since Kamuro's evaluation of Ichinose is high she can't believe that Ichinose would have the same problem as her. Later Sakayanagi asked Kamuro why she didn't ask anything why Sakayanagi is discussing strategies with Ayanokoji which she find suspicious.

In Volume 9 She told Ayanokoji how she met Sakayanagi. A week after the entrance ceremony Kamuro left a convenience store when she met with Sakayanagi. Sakayanagi accompanied her upon leaving then Sakayanagi ask Kamuro if she is shoplifting but Kamuro denied it but Sakayanagi continued her inductive reasoning towards Kamuro's action in which she cannot deny anymore and pull out a can of beer that she had stolen. Seeing how the current situation she told Sakayanagi to just report Kamuro's action to the school but Sakayanagi it and told Kamuro that Sakayanagi had grown to like Kamuro and ask her to be her first friend and that Sakayanagi will hide the shoplifting done by Kamuro in return for her do her some favors with that Sakayanagi will turn blind eye to Kamuro's shoplifting then and in future if she does it again. Sakayangi told Kamuro that her instructions will be anything but boring and can replace the thrill Kamuro find in doing shoplifting. Later revealed by Ayanokoji in his reasoning that Kamuro was used by Sakayanagi to lure Ayanokoji to take action to save Ichinose by telling him the same problem that Kamuro and Ichinose did.

She noted how much has grown since the last time she saw him and states how she will continue to look forward to their next encounter, while also expressing her desire of making him hers.
