Plot
He made his debut in Volume 7 during the meeting between Professor Ayanokōji and his son, Kiyotaka Ayanokōji. He told Professor Ayanokōji that according to the rules of the school, Kiyotaka can't leave unless it is his own wish or that he is expelled. He later also revealed that Kiyotaka was given admission to the school under his approval.

In Volume 10, he was placed under house arrest due to unknown reasons. As a result, he was temporarily suspended and Tsukishiro was appointed as the acting director of Advanced Nurturing High School.

In Volume 11.5, Kiyotaka contacted him to tell about Tsukishiro who caused his suspension and Professor Ayanokōji wanting to take Kiyotaka back. Chairman Sakayanagi decided to help Kiyotaka with assistance from Sae Chabashira and Tomonari Mashima. Chairman Sakayanagi asked Kiyotaka about what he will do after graduating and hopes Kiyotaka will enjoy the 3 years at the school.

In Year 2 Volume 4.5, Tsukishiro said he had been dismissed from his position of Acting Director and Chairman Sakayanagi would return to office.
