Oyuki

Oyuki is the queen of Neptune which in the series is a frozen snowy planet populated entirely by women as most of the men have to go offplanet to find work. As a child she used to hang out with Lum Ran and Benten when they were all in grade school. She is clearly patterned after the yukionna literally snow woman of Japanese folklore. As such she has the power to control and create ice snow and extreme cold. Typically dressed in a long elegant kimono Oyuki is softspoken regal in demeanor and very slow to show anger. However once roused to actually display her abilities she proves to be the most powerful character in the series. Because of the wrath she displays when angered Oyuki is the only person in the entire galaxy that Ran genuinely fears.
