Both Gilgamesh and Chaldea hold a meeting to determine how to fight Gorgon. Merlin explains that Gorgon is the final form of Medusa, driven mad from being cursed by Athena, constantly being hunted by humans, and devouring her own sisters for power. They theorize her ability to birth demonic beasts was a power granted by the Holy Grail. Seeing the divisions within the Three Goddess Alliance, Gilgamesh tasks Ritsuka with convincing Ishtar to join forces with them. Ana recovers from her wounds and rejoins the group. They head to Mt. Ebih to meet her and exploit her weakness for gemstones by offering 25% of Babylon’s treasury in return for becoming Ritsuka’s Servant, to which Ishtar agrees. Roman questions her about her nature as a Pseudo-Servant possessing the body of a human, and Ishtar explains that she and her human host have merged into a single entity with both halves coexisting. That night, Ishtar confides to Ritsuka that she is part of the Three Goddess Alliance because she does not agree with humanity’s decision to abandon the Age of the Gods, since she wants humans and gods to coexist peacefully.
