Aiolia, Aldebaran and Milo have successfully destroyed the Great Root barrier surrounding Yggdrasil and no longer have their Cosmo drained, although at the cost of Milo's life. Entering Yggdrasil while Andreas orders the soldiers to stand aside, The Gold Saints reunite at the center of Yggdrasil, where Lyfia remembers something she once read. Realizing that unless the statues in the 7 chambers of Yggdrasil aren't destroyed, they are unable to destroy the tree.
Before the God Warriors leave to battle the Gold Saints, Andreas bestows them new Odin Sapphires with a significantly greater power which should leave the Gold Saints' God Cloths useless. According to him, the Gold Saints have been revived by Hades who's fighting Athena, naming the battle Ragnarok. As they leave, Frodi asks Andreas about one Gold Saint who has yet to reveal himself. This leads to a flashback showing that Sagittarius Aiolos once confronted Andreas shortly after his revival in Asgard.
Splitting up, each of the Gold Saints head for a chamber; Aiolia is challenged by Frodi at Vanaheim, Aldebaran meets Heracles again at Jotunheim, Mu confronts Fafner at Svartalfheim, Shura challenge Camus at Jaheim and Dohko finds himself confronted by dozens of dead warriors in Helheim, with Shaka, Saga and Deathmask making way to Yggdrasil as well.
In another one of Andreas' flashbacks, Aiolos is caught off guard as roots of Yggdrasil stops his movements, allowing Andreas to launch devastating blows that damage Aiolos' Cloth greatly. Still standing up against him, Aiolos burns his Cosmo and his bow changes form. Clashing with their attacks, Aiolos succesfully breaks through Andreas' defenses and wound him. Andreas then reveals scars on his left eye as the Gold Saints prepare to fight Camus and the God Warriors guarding the chambers.
