Code ABYSS.Ash returns from his trip to the past where he saved Ulku from her initial fate but while he was away, a rumor has been going around in the ARKS. Everyone has been called back to the ships due to an emergency order and Ash notices everyone's strange behaviour towards him, finding out that the rumor is about him. He is approached by Matoi who is worried about him because of the rumor when Xion appears and asks them to go to the heart of the mothership to help her. However, when they arrive there, Regius makes an announcement where he announces that Ash is a traitor and orders every ARKS member to locate and exterminate him by using Code ABYSS.
