Catherine Bloom

Catherine is a talented acrobat and knife thrower in the circus she works in. Many years later, she received training to become a MS pilot. She is a beautiful and kind girl. After experiencing a lifetime of violence, she only desires peace and fears for those in her life who would fight. After meeting Trowa Barton, she developed a familial sense of protection for him, not realizing he's her biological brother. Seeing everything Trowa went through, Catherine didn't like the company Trowa kept, believing they were the corrupting influence for Trowa's behavior.
