I don't think Angel will contribute much to the actual fighting either. I'm just saying it's possible she's not completely helpless.

She certainly might have some motivating effect on Yukino, if their past is revealed.... or she might end up sacrificing herself to save her sisters live by jumping in front of an attack.... that is if they really are sisters. I strongly believe so, but it's not yet proven.
