Yumemi Yumeno:

Yumemi Yumeno was a famous artist who appeared in episode 028 of the anime. Usagi, Naru, and Umino went to one of her art exhibitions where they were able to see a wide variety of her famed illustrations. Naru and Umino showed Usagi a "self-portrait" of Yumemi, and told her that the artist was reclusive, mysterious, and very beautiful. However, no one ever saw her and lately, she had not been producing as many works, leading some people to speculate that she was in a slump. They also told Usagi that Yumemi's drawings were "illustrations of love," and many people believed that owning one of them could make your romantic dreams come true. Meanwhile, the real Yumemi quietly snuck around the exhibit, examining the various couples who were in attendance, looking for models for illustrations. When Yumemi went outside, she bumped into Mamoru. She immediately became very excited, and begged him to be a model for her. Usagi saw Mamoru and Yumemi talking, and became very upset because Mamoru was supposed to be dating Rei at the time. When she went outside to yell at Mamoru, Yumemi asked her to model as well, saying that they fit her picture perfectly. She invited the pair to her house, and they reluctantly went. After Usagi and Mamoru left Yumemi's house, Usagi noticed that the Moon Stick was reacting to a Nijizuishou carrier... and that the signal was coming from Yumemi's house. By the time she arrived, Zoisite had already extracted the Nijizuishou from Yumemi and caused her to transform into the youma Binah. Fortunately, Sailor Moon was ultimately able to heal Binah with Moon Healing Escalation, and she was returned to her normal form as Yumemi.

Later, Yumemi invited Usagi and Mamoru to the Juuban Gallery after her art exhibit had closed. She told them that thanks to Usagi's kind words, she finally had the self esteem to stop hiding from the public. She then showed them a new self-portrait, this one much more realistic than the previous one.

Yumemi only made one other appearance in the Sailor Moon series, in episode 041. Endymion, who had been brainwashed and was working with the Dark Kingdom, was attempting to capture all seven former Nijizuishou carriers and trap them within the Kurozuishou. The Dark Kingdom hoped that although the former youma had been healed by Sailor Moon, they would be able to use their energy and the power of the Kurozuishou to transform them back into youma. After they were reunited, it was hoped that they would come together to form one extremely powerful youma to destroy the Sailor Senshi. Endymion was able to capture six of the seven former Nijizuishou carriers (including Yumemi) within the Kurozuishou before Sailor Mercury destroyed it. Once it was destroyed, those trapped inside were freed and were able to return to their normal lives.

Yumemi Yumeno's seiyuu was Yuriko Fuchizaki.
