We practice a version of Ananku, but being that I just began my journey in the martial arts not too long ago, I don't exactly know how to describe it as well as everyone else. I do know, however, that the above description is not the same we do (not saying that it's "wrong" or anything.) What I can tell you is that after the opening, the first move is to step out with your left leg into a 45 degree angle, slide your right leg up to your left leg and drop into cat stance while executing a shuto. Then you do the same on the right side. Yeah, I know I explained it weird, but hopefully someone will recognize it and be able to give me more information on it. If anyone knows anything about this rendition of Ananku, please respond here or PM me. I am very interested in this kata because it's quite different from the rest I've practiced so far.
