This ended up better than I expected! Also found a friend with a variety of martial arts experiences to help out!
My, not in depth, research on Saifa ended up kinda short. It seams no one knows who created it and Wikipedia suggests it may have been created by Miyagi (since the other branches of Naha-te don't use it). Its name being another death metal album title that says very little to me in terms of intention or objectives.
