Chizuru Tachibana (橘千鶴, Tachibana Chizuru) is the principal of Mihama Academy.
During Yuuji Kazami's time with the Bushdog Platoon, he saved Chizuru from being held hostage by a terrorist, shooting her captor in the hand and incapacitating him. After the incident, Chizuru introduced herself to Yuuji as a "school principal", and offered to grant him any request within her power as thanks. Yuuji said to her that he wanted to go to a normal school and live a normal student life, a request she would later grant by allowing him to transfer to Mihama Academy.
Since his transfer, Yuuji has used his shared past with Chizuru to get her to comply with a number of odd or hard to meet requests, from getting proper vaccinations for Nyanmel to ordering a private jet to the United States to pick him up from the Mihama grounds.
