Background: She met Trowa in the circus where she was working. He act involves knife throwing, and at one time, Trowa was the other half of her act.

Personality: Cathy is very protective of Trowa, and doesn't want him to go to war or get hurt. She feels he has been hurt enought already and would rather keep him at the circus. She became very close to Trowa once she met him, and for a time Trowa called her his sister, although it has not actually been proven that they are related. Her brother, Triton Bloom is thought to be dead, but may be Trowa.
