Medieval tour
This story begins with the heroine Qimai, an ordinary student in the first grade of high school. An accident brought her into the field of COSACT.
Setting introduction: cosact, which can be called character performance, often refers to animation characters, especially Japanese animation. It is similar to the popular cosplay, with a slight emphasis on repertoire-style performance, and the other characteristics are the same as cosplay.
Cosplay is still a luxury that has not been adapted to daily life, but because cosact has more elements of acting (performance), it can be accepted as a school club and has less commercial elements.
