History
The Red Circus started as a student movement advocating for peace and equality, who were speaking out to protect the weakest members of the society. They were a respectable movement that fought for their cause with respectable means, but the state turned violent against them and ordered to have them eliminated.

Over time, they became an organization that sought revenge and justice against the government that wronged them. Eventually, they caught the attention of the Garden, who dispatched the Thorn Princess to their hideout to kill everyone there.

Trivia

 * The Red Circus is a leftist, possibly communist, group. Besides the "Red" in their name being associated with socialism and communism, in non-English versions of Chapter 69, the SSS Boss describes them as a far-left group. In later chapters of the Red Circus arc, Billy Squire mentions that their ideology is all about equality. He also seems to have a disdain for the upper-class, including Eden Academy students and their parents.
