Masumi Kamuro/Relationships

Arisu Sakayanagi
Kamuro is part of the Sakayanagi faction within Class A, and is Sakayanagi's right hand.

In her short story in Volume 6, Sakayanagi can be seen teasing Kamuro and also indicates that Kamuro is ordered to monitor Kōhei Katsuragi but after he withdrew from the contest of leadership for Class-A Sakayanagi ordered Kamuro to monitor Ayanokōji next.

In Volume 7.5 Kamuro searches for Sakayanagi and finds her having a chat with Ayanokōji at the mall. Upon meeting them, Sakayanagi asked Kamuro about her thoughts on Honami Ichinose, to which she replied that she thought Honami was an honors student, however, Sakayanagi told her that Honami had the same problem as her. Since Kamuro's evaluation of Honami was high she didn't believe that, but later, Sakayanagi asked Kamuro why she hadn't asked the reason that Sakayanagi was discussing strategies with Ayanokōji which she found suspicious.



In Volume 9, she told Ayanokōji how she had met Sakayanagi. A week after the entrance ceremony, Kamuro had just left a convenience store when she met Sakayanagi. Sakayanagi accompanied her upon leaving and then asked her if she had been shoplifting. Even though but Kamuro denied it, Sakayanagi continued her inductive reasoning towards Kamuro's action due to which she could not deny anymore and pulled out the can of beer that she had stolen. Observing the current situation she told Sakayanagi to just report her action to the school but Sakayanagi rejected it and told Kamuro that she had grown to like her, and asked her to be her first friend. She then said that in return for some favors, she would turn a blind eye to Kamuro's shoplifting that time and in future instances as well. Sakayangi told Kamuro that her instructions would be anything but boring and can replace the thrill Kamuro found in shoplifting. Later, it is revealed by Ayanokōji in his reasoning that Kamuro was used by Sakayanagi to lure him to take action to save Ichinose by telling him about what Kamuro and Ichinose both had earlier done. .

Kiyotaka Ayanokōji
In Volume 9, Kamuro "forced" her way into Kiyotaka's room after meeting him in the hallway and saying she wanted to talk to him. She told him about how she had met Arisu and about Honami's past, probably on Arisu's orders, as revealed later in Kiyotaka's reasoning.
