They were sent by the Amazoness Quartet to "play" with Minako. They set up an idol competition which Minako participated in order to infiltrate the Dead Moon Circus. They used their skills in knife throwing to immobilize the other senshi and tried to kill Minako. Both of them were destroyed when Minako was finally upgraded to a Super Sailor Senshi, thanks to Artemis, and she used her new attack Venus Love and Beauty Shock.
