Story Role / Major Arcs

Early Class D Activities

On the bus to school, Ayanokoji is noticed by Horikita after both decline to give up a priority seat. He later meets her at a café, where Kushida's apparent coincidence interrupts their conversation. 1 9

During the midterm aftermath, he questions the circumstances surrounding Sudo's failing score and works with Horikita to investigate the video and messages connected to Sudo's expulsion. Their surveillance search produces no clear suspect. 19 27

Framing and Expulsion

Long Aotian manipulates the school point system to place 39,030,000 points in Ayanokoji's account, then uses the balance to accuse him of hacking and theft. Ayanokoji argues that he has been framed through an artificial transfer, but the Student Council authorizes a search of his room. 29

The search finds planted electronic evidence and records associated with school-system access. Kushida then supplies a uniform bearing male fingerprints as alleged evidence of misconduct. With no proof to counter either accusation, Ayanokoji is expelled and referred to the school authorities and police. 30

Return to Class D

Ayanokoji later returns to Class D. He explains to Horikita that the accusation involving Kushida was ruled a misdiagnosis after investigation, causing the expulsion penalty to disappear. He identifies Long Aotian as the person responsible for framing him. 40 41
