Background / History
Class A initially held the highest first-year designation but had no settled leader when Yuki Gyakukai of Class B approached it with an offer to sell hidden school rules. Its students collectively considered the offer, with Kouhei Katsuragi acting as spokesperson while Arisu Sakayanagi challenged the reliability and limits of Yuki's information. 12 13
The class purchased five rules at an average price of 388,000 personal points each, paying Class B 1.94 million points. The agreement required Yuki to provide genuine rules under threat of expulsion for fraud, while binding Class A not to harm Class B for one month or disclose the purchased rules to other classes. 13 14
The information revealed that only Class A graduates receive the school's promised advancement and employment benefits; that class and personal points determine rankings; that 20 million personal points can enable transfers or avert expulsion; and that special exams can adjust points and expel students. 13
Despite its strong discipline and collective willingness to invest in class interests, Class A was internally divided between the Katsuragi faction, the Sakayanagi faction, and neutrals. Observers also noted a significant number of loners among its students. 11 14 47
By May, Class A stood at 860 points while Yuki's former Class B reached 980 and was officially promoted to Class A. The original Class A was subsequently identified as Class B under Katsuragi. 26 27 47

Story Role / Major Arcs
Hidden Rule Transaction
Class A served as Class B's first outside customer for its knowledge of the school's hidden rules. Its students demonstrated cohesion by submitting individual price offers, accepting the calculated average, and signing a binding contract rather than relying solely on Yuki's word. 12 13
Rival-Class Assessment
After the transaction, Class B judged Class A to possess stronger discipline and a more aggressive mindset than its competitors. Its lack of a unified leader and visible loners were identified as potential weaknesses despite the class's overall quality. 14
Demotion and Midterms
Its point total of 860 placed it below Yuki's former Class B, which reached 980 and claimed the Class A designation. As Class B, Katsuragi's class later achieved a clean midterm pass rate and earned 73 class points. 26 27 47
