Dead Moon Circus
The Dead Moon Circus (デッド・ムーン・サーカス) was a circus which served as a front for the operation of the Dead Moon, the main antagonist group in the SuperS season of the anime and the Dream arc of the manga, as they searched for Pegasus and the Golden Crystal. The performers in the circus were all either Lemures or members of the Dead Moon, such as the Amazon Trio or the Amazoness Quartet. The ringmaster of the circus was Zirconia.
In the musical Sailor Moon SuperS - Yume Senshi - Ai - Eien ni... and its revision, the Sailor Senshi were invited to audition to become performers in the circus. They all got in with the exception of Usagi, who showed herself incapable of performing any circus trick.
