The abbreviation SRT stands for "Special Response Team". An elite school that possessed authority from the General Student Council president to mobilize freely around Kivotos. However, following the GSC President's disappearance, the school was neglected and the decision to shut it down was made.
SRT Special Academy was originally an elite school, acting as the special forces command of Kivotos, and armed with the most advanced equipment in the city. Unlike Valkyrie Police Academy, SRT was given special authority by the GSC President, allowing them to mobilize anywhere, at any time, to respond to crime. However, following the disappearance of the GSC President, the school became unmanageable, after which a movement within the GSC began to shut down the school.
The General Student Council eventually decided to shut down the school, with rumors spreading around the press that a previous commotion at the Sanctum Tower had something to do with the decision. This is later confirmed to be an incident during the closure movement, in which the FOX Platoon assaulted GSC members that supported the movement and even destroyed a portion of the Sanctum Tower in the process. This incident served as the final nail in the coffin, and the decision to merge SRT with Valkyrie was made. However, not all students were satisfied with the decision and refused to transfer, holding a public protest within Usagi Park. They continued to live there under Sensei's suggestion after being given the authority to decide SRT's fate by the chief of the GSC's Defense Office, Shiranui Kaya. Sensei also indirectly provides them food by letting them have Angel 24's disposed near-expiration bentos and provides them with other supplies using their credit card.
