Originally she held a hatred towards humans when her parents were killed in an car accident while the family was vacationing . Ruby was originally part of a plot to destroy mankind as a response to a large garbage dump polluting her mistress' sanctuary. However, after meeting Wataru and the others, she has foregone this trait and even turns against her master. She became Wataru's new maid and now resides in Castle Doran with the other three residents: Jiro, Ramon, and Riki.
Apparently, Ruby has shown that she is a masochist and the biggest pervert of them all when Kurenai gives Kokoa a spanking for attacking his home on chapter 34. She shows to have a large number of perverted traits which, aside from deriving sexual gratification from pain, generally involving her being tortured by Wataru in various ways like spanking her for example.
Powers and AbilitiesEdit
Ruby is a very powerful Witch. Much of Ruby's magic revolves around a motif of ravens and flora, both as familiars and alternate forms for her to take. It should be noted that Ruby's flora looks similar to Biollante, an enemy of Godzilla.
By using this skill, Ruby is able to transform herself into a crow. This is useful when she has to follow a person or group without raising undue suspicion.
Ruby has also displayed the ability to partially transform herself into a crow, which gives her three pairs of crow's wings on her back. She is able to use these wings to fly or hover in mid-air. She also seems to be able to extend the feathers of her wings and use them as blades to cut into enemies.
