Phantasy Star Online 2: Episode Oracle

Synopsis

Luther has become a Dark Falz and he easily overpowers Ash and Matoi. Before he is able to finish them off, the Council of Six (except for Klariskrays) and Quna come to their aid and battle Luther. Luther tries to get Regius to his side by using Alma but he angers Regius instead who defeats him by using World Ender Yonohate. The ship starts to fall apart and everyone retreats but not before Ash, Matoi, Regius and Maria see Dark Falz Gemini eating Luther and using clones of him to stop them. They successfully retreat and the ship gets destroyed. With the threat gone, ARKS go back to their regular duties but not for long.
