Chairman Sakayanagi/Relationships

Arisu Sakayanagi
Mr. Sakayanagi has a close relationship with his daughter.

Professor Ayanokōji
Even though Mr. Sakayanagi doesn't entirely agree with his vision on education and nurturing, he still shows respect towards him, even calling him sensei.

Kiyotaka Ayanokōji
Chairman Sakayanagi has known Kiyotaka for a long time and it was mentioned that he considered him a special student. Unlike other students in the Advanced Nurturing High School who were already selected prior to their application, Kiyotaka was accepted to the school without any recommendations, thanks to Chairman Sakayanagi's approval.

In Volume 11.5, Kiyotaka contacted him and told him the truth about Tsukishiro and his father, Professor Ayanokōji. Chairman Sakayanagi decided to help Kiyotaka and recommended the two teachers, Sae Chabashira and Tomonari Mashima, for assistance. He asked Kiyotaka about what he will do after graduating, and hopes Kiyotaka will enjoy the 3 years at the school.
