Phoenix Wing: Rettenjō

Phoenix: Rettenjō is of unknown shape. There is a possiblity 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).

Trivia

 * In Jin´s gag reel, one of Jin´s rankings shows two Nox weapons; Bolverk and Nirvana, as well as Bang´s nail. So it can be assumed that the Phoenix: Rettenjō is the giant nail.
