Background

Class A began as the school’s elite first-year class, but its position was not permanent: class rankings changed according to cumulative class evaluation scores, and only students graduating from Class A received the school’s full promised advantages. 1 8

The class’s first-month result demonstrated both its strength and its vulnerability. It retained first place with 836 points, yet Totsuka Yahiko’s decision to punch Ryuuen Kakeru during Class C’s harassment campaign was treated as a behavioral violation. Katsuragi accepted responsibility for the loss and focused on recovering through later special exams. 8

From early on, Class A was split between Katsuragi and Sakayanagi. Katsuragi considered Sakayanagi highly intelligent but opposed her aggressive, self-interested approach; by the time the factions solidified, his side held 25 students to her 15. 8 53

Major Arcs

Behavioral Norms Exam

  • Class A lost 164 of its initial 1,000 points, but its 836-point total still placed it above Class B’s 710, Class C’s 503, and Class D’s 0. 8
  • Class C, led by Ryuuen, harassed Class A students through nuisance calls and stalking. Totsuka retaliated by punching Ryuuen, worsening the class’s conduct assessment. 8
  • Totsuka later paid Ryuuen 500,000 private points to attack other classes, an unauthorized scheme that Nakano Yuu exposed. 38

Academic Exam

  • Katsuragi distributed past exam papers throughout the class, allowing Class A to achieve perfect scores and claim the exam’s full 100-point reward. 69
  • Ryuuen recognized that forcing an entire class to memorize the material and achieve perfect results demonstrated Class A’s organizational strength. 69

Island Exam

  • Class A and Class C purchased cameras and binoculars from Nakano Yuu to scout the island before the exam began, preventing Class B from obtaining the same reconnaissance advantage. 89 90
  • Katsuragi and Ryuuen formed a temporary alliance to suppress Class B and monopolize Class D’s supplies. 96
  • Their strategy failed when Nakano revealed that he had cooperated with Class B in exchange for 70% of its supplies; Class A and C then incurred deductions for taking supplies from Class B-controlled strongholds. 101
  • Katsuragi accepted Nakano’s offer involving the hidden base and Hirata’s leader status only after Classes B and C agreed, fearing that refusal would leave Class A further behind. 116 117
  • Ryuuen ultimately betrayed the alliance by correctly identifying Class A’s leader, contributing to Class A’s fall to Class B after the exam. 118 119

VIP Exam

  • Following the Island Exam, the former Class A was designated as Class B, while Ichinose Honami’s class held the Class A designation. 117 128
  • Katsuragi and Sakayanagi continued to operate as separate power centers; Katsuragi could not independently commit the class to purchasing VIP information without Sakayanagi’s approval. 141
  • The class purchased a VIP-information slot from Nakano Yuu as part of the three-way information contest between the upper classes. 141
  • During the Dragon Group discussions, the class’s representatives were Katsuragi and Sakayanagi, with Sakayanagi regarded as the more offensively dangerous of the two. 171

Sports Festival

  • The class, now known as Class B, entered strategy talks with Class D concerning the Sports Festival. 169
  • Katsuragi questioned whether Class D would genuinely cooperate and examined its Tian Ji horse-racing-style roster, which divided competitors into seeded contenders, ordinary students, and cannon fodder. 169 179

Relationships

  • Class C — Competitive rival. Ryuuen’s harassment, alliance proposals, and eventual betrayal repeatedly damaged Class A’s position. 8 96 119
  • Class B / Ichinose Honami’s class — Initially a rival class known for unity and vigilance; it outmaneuvered Class A during the Island Exam and subsequently took the Class A designation. 38 101 117
  • Class D — Initially viewed as far below Class A, but Nakano Yuu repeatedly profited from and manipulated Class A’s strategic decisions. 84 89 101
  • Nakano Yuu — A Class D student regarded by Katsuragi as a potential danger to Class A due to his information trading, Student Council connections, and ability to manipulate other classes. 26 69
