Fujimaru successfully retrieves Gilgamesh's clay tablet, and within a deep slumber, he remembers his encounter with the King of Mages in London, the Fourth Singularity, which renews his understanding of the importance of the final Holy Grail. Meanwhile, Merlin suspects that the Demonic Beasts at the Northern Wall are planning a large-scale attack, and takes Fujimaru and company to the Northern Wall. There, they see a squad commanded by Leonidas I putting up a struggle. Once there, Fujimaru and company hear from Ushiwakamaru that communication with the fortress city of Nippur to the north has been severed, and they head out towards Nippur.

Fujimaru and entourage have lost Ushiwakamaru and Leonidas I. Upon receiving the report from the group that returned to the ziggurat, Gilgamesh decides it is necessary to conquer the three goddesses in certain order to fight against Gorgon, and orders Fujimaru to first turn Ishtar into an ally. With a "secret plan" given by Gilgamesh in hand, Fujimaru and company head over to Ishtar's temple.
