Which AA is the one I see running around with knives? I've seen it in several flash movies, usually red in color. I think I remember seeing someone calling it Ahya but I cannot remember.

The one I was wondering about was in fact the one that resembles Shii, yet red in color and usually is seen with or throwing knives at the other AA characters. So her name is Tsuu? How did she come about anyway? Sorry, so many questions! ^^
