AppearanceEditIn fact, the Anti-Angel Headquarters is actually the Principal's Office. It is a squarish office with a large wooden desk and a tall computer chair which is right in front of the double door. Two single-seat sofas, one triple-seat and a coffee table can be seen in front of the desk. A few cupboards and paintings can be seen at the corners of the room. Photos of past and "present" (who is actually Yuri) principals are hung around the windows at the back of the principal's desk.
With the first members of SSS, the take-over of the Principal's office was the battlefront's first large-scale operation. By this time, Hinata, Yuri, Ooyama, Noda, Chaa, Shiina, Iwasawa and Hisako were the current members. While Iwasawa and Hisako were to perform their first guerilla concert, Shiina and Chaa were also tasked divert attention using Shiina's dexterity and Chaa's frightening appearance. Hinata, Yuri and Ooyama themselves secured the location, distracting the faculty members and transferring the seats. Noda served as guard for the diversionary forces as the actual transfer takes place.
