Phoenix Wing: Rettenjō

Phoenix: Rettenjō is a giant 55-inch nail. It is believed to possess the power to destroy other Nox weapons, sever ties with the Boundary and destroy the world. The core of Rettenjō is Kushinada's Lynchpin. Trinity Glassfield is the only person alive who knows its whereabouts, as it was believed to have been lost after the Dark War, when in all actuality, it was in Lord Tenjō's possession. Before Tenjō's untimely demise at the hands of Jin Kisaragi, Tenjō gave Rettenjō to Bang Shishigami, who is unaware of its power.
