Due to overwork, Gilgamesh finds himself in the arms of eternal sleep. Fujimaru and the others are shocked by the news. They also hear from Siduri that there have been many reports of deaths from weakness within Uruk. Thinking that a member of the Three Goddess Alliance is the cause of it all, they head to the underworld with Ishtar to defeat the goddess of the land of the dead and liberate Gilgamesh's soul.

After making peace with Ereshkigal, the goddess of the underworld, Fujimaru and the others return to Uruk to find Gilgamesh who has returned to the land of the living. As the final battle with Gorgon approaches, Gilgamesh proposes a strategy that may give them a chance at victory. His plan calls for a preemptive strike on Gorgon's stronghold, the Blood Fort, before she can begin her next attack on humanity. Before the battle to decide Uruk's fate, Fujimaru speaks with Merlin and Ana as they travel to the Northern wall.
