Plot
In Second Year Arc Volume 1, Class 1-D's Kazuomi Hōsen along with Nanase went to the second year floor in the school building and made way to Class 2-D. Suzune Horikita offered to be in equal footing with 1-D but Hōsen wanted Class 2-D to submit to them talking as if he is the senior student. The situation became troublesome, making Nanase stop Hōsen, saying she would reveal "that" to everyone in the vicinity and they left.

She met Kiyotaka Ayanokōji going to school the other day. Ayanokōji asked her if she found a partner yet and they talked about class 1-D. She talked about violence which partook to Hōsen's approach and told Ayanokōji that she would never succumb to it, then they exchanged contact info and talked about setting a meeting later on.

The next day, Nanase met up with Ayanokōji and Horikita at the library talking about how to negotiate possible pairings for the special exam, but it seems that Hōsen's control over the class was superior that even Nanase could not betray. She contacted Hōsen to talk about the contract that Horikita wanted with 1-D but was flatly rejected by Hōsen. Nanase seems to accept the contract but had no power to refuse Hōsen. The next day she came to the library again and proposed for help for possibly replacing Hōsen as the class representative but Horikita refused her offer as she believed that as long as Hosen was persuaded then all their problems would be solved easily. Nanase agreed with her and admitted she lied about offering to be the leader saying she had the same idea as Horikita and promised she would bring Housen to a meeting on Sunday. After Horikita left, she asked Ayanokōji a personal question about who he was, but Ayanokōji didn't answer which made Nanase say what she thought of him as a wicked and filthy person. When Ayanokoji asked if she saw him as a person who wasn't ordinary she immediately backed down and apologized saying that the current priority was the cooperation of classes. Then she told Ayanokōji that the actual points initially given to the first years were only 800,000 points only which is 200,000 less compared to what the second year had received last year. In return for the information, Ayanokōji told her about the existence of the Protection points.

She arrived at the karaoke with Hōsen on Sunday night with the same contract offered to her by Horikita previously, but Hōsen still rejected the proposal which caused Horikita to stop negotiating with Hosen and they both left the karaoke. After leaving the karaoke they went to the back of the dormitory for the first-years and the negotiation continued, but it turned into real trouble as a brawl between Sudō and Hosen began. After some time when Hōsen turned his knife toward Ayanokōji, she appeared to stop Hōsen, saying that even though she hated Hōsen's way but she's going to lend her strength to the class, even if it meant doing it in an ugly way, but she had enough of it. After Hōsen's defeat, she told Ayanokōji that along with the special exam there was a condition that if someone could make Ayanokōji drop out, they would be given 20,000,000 private points and that only a few first-year students knew about it, but also admitted with hatred in her eyes that she had another reason for helping Housen and that was because she didn't believe a person like Ayanokoji was suited to be in a school like this, before leaving the place.

In Volume 2 she teams up with Housen and Ichika Amasawa in order to expel Ayanokoji in the next Island Special Exam.

At the end of Volume 2, it is revealed that she has been working under Tsukishiro's orders to get Ayanokōji expelled.
