Ayanokōji

Biodata

Background / History

Ayanokōji enrolls in Tokyo Metropolitan Advanced Nurturing High School as a member of Class D. On the first-day bus ride, he sits beside Horikita Suzune after briefly looking over both her and Kamigami Haruo. Haruo’s prior knowledge identifies him as an artificial genius produced by the White Room. 3

At a convenience store shortly after enrollment, he pays for Ken Sudō’s items during Sudō’s confrontation with the cashier, then later helps clean up after Sudō’s discarded noodles. His intervention is framed as being influenced by the presence of surveillance cameras. 6

Personality

Ayanokōji appears reserved and passive in social situations. He wants to make friends but does not actively pursue them, and he repeatedly expresses a preference for a quiet, trouble-free school life. 14 21 46

He is observant of surrounding dynamics, including Haruo’s negotiations with Horikita and the consequences of Class D’s point losses. 11 42 Haruo considers him a highly capable but self-interested person who can discard others if doing so ensures victory. 3 46
