Chizuru Tachibana

Chizuru Tachibana is the principal of Mihama Academy and an acquaintance of Yuuji Kazami who is the only daughter of prefectural governor. To her, Yuuji is a benefactor of life, as he rescued her in an event in the past. Because of that reason, when Yuuji told her that he wanted to have a normal school life, she offered him the chance to enroll to Mihama Academy.

Yuuji seems quite fond of teasing her, which has led to her getting rather snappish around him ...
