Viluy

The past of the young woman known as Viluy remains a mystery. As Yui Bidou she is a student at the Infinity Academy, no details have ever been revealed about her private life, neither who she really is nor where she really comes from. It doesn't even tell how she came to be associated with the the evil organization known as the Death Busters or what her motives were for joining them in their sinister quest to purge the Earth of all life by summoning Master Pharaoh 90 and triggering the apocalyptic cataclysm known only as the Silence.

A member of the young female scientists and sorceresses collectively known as the Witches 5, the cold-hearted, pompous and overconfident Viluy was initially shown her way around the laboratory and taught how to perform her job by the group's senior member Eudial and eventually became an experienced computer programmer and brilliant nanoroboticist in her own right, second in her technical expertise. As Yui, she even managed to maintain an extremely impressive academic record, being not only one of the top students at the Infinity Academy with grades and test scores comparable to those of Amy, but also serving as the president of the Science Club as well as a teacher there.

Viluy was the fourth of the Witches Five who used her skills in electronics and computers and used them to find and extract the Heart Crystals from pure hearts of people, not to mention to find the Three Tailsmans.

With the upcoming pre-high school entrance exams which were to be electronically written at the Infinity Academy in the near future, Viluy devised a plan where she would use a combination of the private school's computer network and nano robots of her own creation and design in order to extract and collect the Heart Crystals of all the participants attending.

When the exams were well underway, as Yui, she went to investigate a security breach in the underground laboratory of the Infinity Academy that served as the sanctum of the Messiah of Silence. She confronted Amara, Michelle and Amy. Amara and Michelle had come to eliminate Hotaru before she fully revived. Yui transformed into Viluy and attacked Amara and Michelle with her nano robots. Amy then transformed into Sailor Mercury and fought against Viluy's robots, freezing them with her "Shine Aqua Illusion". Then the other Sailor Scouts arrived and Super Sailor Moon used her "Rainbow Moon Heart Ache", severely damaging her opponent's control bracelet in the process.

Viluy had no idea her nano robots were damaged as much as they were and ordered them to attack Super Sailor Moon. Unfortunately they attacked her instead and Viluy suffered a slow and painful death at the hands of her own nano robots as they took her apart molecule by molecule. The Sailor Scouts were left with no choice but to watch her death from a safe distance with more regret than any sense of triumph, unable to approach the young witch without running the risk of sharing in her fate. After Viluy was finally consumed by her own malfunctioning creations and vanished into nothingness, Sailor Mercury expressed her pity for Viluy and the unfortunate fate she endured. She appears in Sailor Moon S, Episode 103.

Viluy's voice is played by Yoshino Takamori.
