Wow! That looks awesome so far. I'll see if I can provide an image giving an idea.
EDIT: The best I can do is this video here, which demonstrates Unlimited (SNK Boss Version) Ragna, who is doing what I am looking for. It also has many of his moves that kind of demonstrate what his energy looks like.
And if there is one change I'd ask for if it is not too much trouble, would you be able to give him his Hakama (the pants) and use the OotS-style boots?
