Yuusaku also grew up together with Madoka and Hikaru and is in love with Hikaru. When they were smaller, she told him that she wouldn't be interested in him unless he became stronger and more masculine. Thus Yuusaku trained heavily in martial arts. By the time he achieved proficiency, Kyousuke has arrived on the scene and Hikaru is head-over-heels in love with Kyousuke. He, naturally, regards Kyousuke as a rival in love for Hikaru. Thus, the relationship between Yuusaku and Kyousuke is a bit strained.
Zirconia appears as an ugly, insectlike old woman with lavender skin. Secondary to Queen Nehellenia, she controls the Amazoness Quartet and the Amazon Trio. Her name is derived from the mineral zirconium dioxide, which is often called zirconia. She first appears in Episode 128 of the anime and Act 34 of the manga. In the English-language adaptation Zirconia's gender was changed from female to male. In the anime, Zirconia looks the way Nehellenia would look if she were old, and thus she haunts the queen's dreams. Zirconia is the personification of Queen Nehellenia's nightmares, given form to lead the Dead Moon Circus to find Pegasus and carry out the Queen's revenge. She commands the Amazon Trio to go to earth and seek out those with beautiful dreams, who might have the Dream Mirror in which Pegasus is hiding. She uses Zircon, a flying eyeball that usually sits atop her staff, to gather images of those with beautiful dreams, which she gives to the Amazon Trio as their targets. She soon becomes impatient with the Amazon Trio, and allows the Amazoness Quartet to send lemures to kill them. She then sends the Amazoness Quartet to do what the Trio failed to accomplish. In the manga, the Amazon Quartet calls her baa-san, meaning "grandmother" or "old woman," and she acts as a mediator between them and Nehellenia. Like the other members of the Dead Moon Circus, she doesn't like light, and feels comfortable only in darkness. She speaks to Nehellenia through the mirror, complimenting her often. Little is known about her motivations, but the most important thing to her is to figure out how to make Nehellenia's plans work. Her first mission for the Quartet is to make sure that the circus is a success on Earth, and then taking over everything for the Dead Moon Circus, little by little. She tells them to proceed cautiously when dealing with the Senshi, and lets them know that she will not tolerate a failure. In order to conquer the Earth, she says, they must first destroy the Senshi by filling them with nightmares.
Fisheye takes the form of a slender, effeminate male with long, pale blue hair. In the anime, like Tiger's Eye and Hawk's Eye, he targets his ideal romantic interests, which are young males. His magical attacks are water-based, but his primary choice of attack is knife-throwing (which, to his frustration, he is not very good at). Crossdressing is the basis of many of his disguises, as he is usually able to pass himself off as a woman to attract his targets, who are generally heterosexual males (he portrayed his gender honestly to the one gay target he had). Unlike his cohorts, who are rather superficial about their victims, Fisheye seems to nurse a paradoxical genuine affection for many of his victims (or at least a childish crush) until they give him the inevitable brush-off. This included the kindly Mamoru Chiba, who he seemed to develop feelings for and even kissed. Fisheye is also the first of the three to wonder if what they are doing is right, and his wavering loyalty lands him in hot water when he is nearly killed by Zirconia. Midway through the series, he and the others are sublimated into Pegasus' world and given the promise of rebirth as real humans. Fisheye has a very small part in the manga, in which he is sold to Ami Mizuno in fish form. He gives her nightmares about her father abandoning her, luring her into a trap. She powers up and defeats Fisheye with Mercury Aqua Rhapsody, and he is killed soon after by Sailor Moon and Sailor Chibi Moon.
