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. .

In 2nd year volume 9.5, Kiyotaka said it is interesting for him that Masumi makes a move because of her class, which Masumi said it is because goal is Kiyotaka and he is the only one who can influence Arisu. Masumi said she is not helping Arisu as she still hates her because of what happened. She only helps because her class might be in trouble in a time.

Masayoshi Hashimoto
Masayoshi are classmates but their personality is different. Masumi is more serious and businesslike but Masayoshi mostly likes to joke and spend time with girls. Masayoshi talks casually with Masumi, enjoys being with her, seems to consider her a good woman and flirts with her. Masumi on the other hand does not like Masayoshi and seems him annoying for joking. She also does not like that he calls her Masumi�chan. Masumi also said she hates Masayoshi's cynical and negative way of thinking. After Masayoshi found out about Kiyotaka's powers, he told Masumi about it, Masumi knew it to some extend and took interest in rest of them. Masumi questioned it when Masayoshi said Kiyotaka is better and stronger than Arisu but Masayoshi said he is sure and won't add possibly or probably. Masayoshi asked Masumi to investigate Kiyotaka which Masumi she will do under one condition Masayoshi don't call her Masumi-chan. After Masumi found Kiyotaka with Hiyori, Masayoshi and Hayato arrived and they walked to find a place to talk. Masumi gets annoyed that Masayoshi sometimes gives mention to stupid romance things like when he said when Kiyotaka is surrounded by beautiful women females of jealousy burns inside of him. When they said Karaoke might be a good choice to go but Masumi rejected which Hayato said it is because Masumi is tone-deaf. Also when Masayoshi wanted to hit on Hiyori, Masumi tried to stop him which caused Masayoshi does she want to become his girlfriend which resulted Masayoshi being kicked. They choose a cafe to talk but Masayoshi asked a stupid question and Masumi kicked him. When Kiyotaka gave answer of he is mastermind of Suzune's class and Masayoshi asked Masumi opinion she said almost certainly but not quite. Masumi also questioned Masayoshi after Masayoshi said Arisu will welcome Kiyotaka to class which Masayoshi said there will be no problem. Then after some talk Masumi wanted to leave since it won't reach anywhere but Masayoshi returned her.

Hayato Kito
Masumi seems to get annoyed with Hayato when he says something about her like in 2nd year volume 9.5 when he said to Kiyotaka that Masumi is tone-deaf so she can't sing and that is why she does not want to go to karaoke and later said Masumi has the ears of demon.

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.

In 2nd year volume 9.5, She become aware of Kiyotaka's abilities after Masayoshi overheard what Kiyotaka's classmates said about him and he told her about it. Masayoshi then asked her to investigate Kiyotaka. Masumi approached Kiyotaka when he was walking with Hiyori and talking about library experiment. Masumi thought Kiyotaka is being Ostentatious. She said she saw him go on a date with Kei in December 29th and now she sees him with Hiyori. Kiyotaka told him details. When asked why she made a move despite hating Arisu she said it is because that Kiyotaka is the only one who can influence Arisu. Masumi then asked Kiyotaka that what was his reason with recent activities. Kiyotaka did not know what she meant. Masumi said to not play dumb and said she thinks Kiyotaka is snooping around Class-A, Kiyotaka remembered a Class-A student named Ai approached him and talked with him. Masumi meant that and asked Is Kiyotaka trying to probe Class-A which Kiyotaka said he isn't and said whenever she believes him or not it is on her. Then Masumi wanted to ask about Kiyotaka being the mastermind of Suzune's class but Masayoshi and Hayato come. In cafe when Kiyotaka answered that he is mastermind in a way that is unclear and Masayoshi asked her what she thinks she said almost certain but not quiet. Masumi also had doubts that Arisu will accept Kiyotaka to class.
