Background / History
Kanzaki is elected Vice Class Leader alongside Ichinose, who receives the class leadership unanimously. He offers to help manage Class B’s finances and becomes one of the students coordinating its daily affairs 8 17 18.
Before the first midterms, Kanzaki organizes a study group for classmates with weaker foundations. He assigns tutors by subject, takes physics and chemistry himself, and suggests using Toudou’s Sanda Club connections to seek past exam materials from upperclassmen 46 47 49. After weighing the cost, he approves a 300,000-Private-Point purchase of study materials; the class uses them to prepare tutoring materials and a mock exam 52 53.
During later class disputes, Kanzaki consistently weighs possible benefits against risks to Class B. He cautions against direct intervention in the Sudo incident without evidence, helps guard class information during the island exam, and works with Ichinose on question-setting for the White Paper Shuffle 68 69 143 269.
Ichinose’s class eventually graduates as Class A. After graduation, Kanzaki joins Toudou’s business group, where he oversees risk control, compliant operations, and process management 390 391.
