Description: Ruby Moon is a guardian created by Hiiragizawa Eriol. She uses Western magic and her symbol is the moon. Her fellow guardian is Spinel Sun, whom she nicknames "Suppi". The name for her false form is Nakuru, a very hyper girl that can often be found clinging to Kinomoto Touya. Her reason for this was not because of romantic intentions, rather, she wants his power, since her power depends on her master's. Because Yue's false form, Tsukishiro Yukito doesn't realize what she wants, Nakuru can often be seen hinting to him in an ominous tone. Nakuru / Ruby Moon actually has no gender, but she wears female clothing because she thinks they're cute. The only reason for Ruby Moon's creation was that she would battle Yue during Eriol's final battle with Kinomoto Sakura. She would be used to keep the other guardian occupied so Sakura would be forced to work alone.
