Ding Feng/ Kaguya - Mystic Weapons | Warriors Orochi 3: Ultimate

An odd choice of characters I admit, but it would be Ding Feng on his own otherwise. Kaguya's moveset is reused in the later title 'Warriors All-stars' for one of the Fox characters which I can't remember the name of because the game wasn't very good.
