Japanese name:	キャスリン・ブルーム
Nickname:	Cathy

Catherine is a beautiful and kind girl. After experiencing a lifetime of violence, she only desires peace and fear for those in her life that would fight. After meeting Trowa Barton, she developed a motherly sense of protection for him, not realizing it's her biological brother. Seeing everything Trowa went through, Catherine didn't like the company Trowa keeps, believing they are the corrupting influence for Trowa's behavior.

After many years after the events of Endless Waltz, Catherine became a different person. She's now adept in the ways of war and has since taken in a teen that has a strong resemblance to Trowa. The extreme change from pacifist to fighter is unknown, but it suggests something of great traumatic event that lead to her change in position and philosophy of life.
