Yoshiki Usui was an anime-only character who appeared in the SuperS season. He was a fashion designer who was targeted by Fisheye as the potential owner of the Dream Mirror which held Pegasus. Usui was in a slump creatively when he was approached by Usagi Tsukino, who asked him if he would design her a wedding dress. Enjoying her companionship, he agreed. He was later inspired by Fisheye, who, despite being a man, Usui felt would be a perfect model for his female clothing line.
Fisheye proved himself to be quite high strung and full of himself, annoying many of Usui's co-workers and causing him to fall out with his main assistant. However, after he realized how silly the designs inspired by Fisheye were (they all looked like fish), Usui became even more disillusioned with himself and confronted Fisheye - who removed his Dream Mirror and discovered that his mirror did not contain Pegasus.
After he was saved by the Sailor Senshi, Usui made up with his assistant, and was then inspired by the short skirts of the Senshi to produce a line of miniskirts. He also designed a wedding dress modelled by a girl who wore her hair in a style somewhat similar to Usagi's.
- In the English dub, Usui's main assistant was said to be his brother. Some fans feel this was done to lessen the implications that Yoshiki Usui may be gay.
