She disappears after her mistress is defeated and put to rest. Ruby then reappears sometime later when Tsukune Aono becomes out of control as a ghoul, and helps the Exorcist in sealing his abilities. She now resides at Yōkai Academy, as the board chairman's aide and continues to work for him.
Ruby has long dark brown hair that is put up in a variety of ways depending on the situation. However, she mostly keeps two ponytails on each side of her head and lets the rest fall naturally. She has what appears to be reddish-brown eyes.
Ruby enjoys wearing corsets and long skirts. Her main corset is pink that stops just above her bust. Black strings then go up and wrap around her neck to make sure it doesn't fall down. On her arms she wears red half sleeves that go from her biceps to her wrists. Her skirts are usually dark in color and don't go shorter than her knees.
Originally she held a hatred towards humans when her parents were killed in an car accident. However after meeting Tsukune and the others, she has foregone this trait and even turns against her master. Ruby also has a crush on Tsukune and looks at Tsukune like a toy. She is very loyal and generally seen as being sophisticated and proper, and having the credentials to fill in as a substitute teacher.
Ruby lives to take orders from others as she is seen doing what others have told her to do. whether its a plan or a simple task; she has never been seen coming up with ideas on her own or ordering others around.
Power & AblitiesEdit
Ruby is a very powerful witch able to fight at the same level (combining her magic with Yukari's) with the leader of the security committee and even being able to wound him. Much of Ruby's magic revolves around a motif of ravens and flora, both as familiars and alternate forms for her to take.
