The Ruler of Darkness! The Terror of Abzu!.Eden tries to stop Abzu with no success until he gets the chance to obtain Aria's staff to confront him. Medea tries to dissuade him, but he refuses to comply and reclaims the staff by force. With Köga's friends failing to get him back to normal despite everyone awakening their Seventh Sense, Eden eventually returns with the staff to the battle, just to find it destroyed by Abzu. Just as Eden is about to be dealt the final blow by the God of Darkness, Medea stands to protect her son, sacrificing herself for him. However, Eden is still dealt a heavy attack while the shards of Aria's staff fall down a cliff.
