Kocho Shuyona is the headmaster at Akademi Highschool.
He has an extreme fear of her.
Due to his fear of Ayano, she is able to send Riko to talk to him a few times. However, depending on the player's actions, he will catch on and stop talking to her or begin fearing her too.
Him and Chie have spoken several times about Ayano, which lead to Chie introducing herself to her.
Akiko is a very trusted student to him, though, the outcome of Hason's and Osoro's weeks can alter how they interact.
Depending on the player's actions, Rina and Kocho may or may not ever interact.
