Kinda ironic, seeing that canonically, Shou has absolutely NO training in martial arts, or weapon usage. Literally, her whole attire, is nothing but for decoration.
Her weapon she does use is rather vicious though (the pagoda beams turn ya to ash! ouch...) and she is an avatar for Bishamonten, so the decorative attire fits. It does make me wonder if Akyuu is going a little askew on her facts again, since you would think a representative of said god would have some martial power ( the other 20% i suppose).
