Phoenix Wing: Rettenjō

Phoenix: Rettenjō is of unknown shape. There is a possibility of it taking after the shape of Bang's gauntlets, giant nail or his belt buckle. It is believed to possess the power to destroy other Nox weapons as well as sever ties with the Boundary, but only Trinity knows what happened to it since the war (Bang is unaware of its power). It was believed to have been lost after the Dark War and it is currently unknown how Bang has obtained it.
