Okito Kanie teaches world history at the high school attended by Hana Natori's cousin. He previously attended the same high school as Hana, making them former classmates. During Hana's first day impersonating her cousin, Kanie recognizes her despite her efforts to blend in, exposing her deception early on. After confronting her about the impersonation, Kanie does not report her. Instead, he proposes to keep her secret in exchange for a physical relationship, leveraging his authority as both a staff member and her former peer. He initiates this arrangement by kissing Hana shortly after revealing his knowledge of her situation.
