Fujimaru's entourage successfully has an audience with the wise king Gilgamesh ruling over Uruk. Fujimaru suggests to Gilgamesh that he wants to receive the Holy Grail that is causing this Singularity in return for defeating the Three Goddess Alliance that is putting all of Mesopotamia into a panic. However, Gilgamesh declares that he will not need the assistance of Chaldea for Uruk to face its perils. The situation turns extremely delicate, but then, Ishtar, the patron deity of Uruk, suddenly intrudes upon them, and they all end up in battle.

Fujimaru and company are dumbfounded by Gilgamesh's sudden visitation of the Chaldean Embassy. There, they are given a new request from the king which is to investigate the Persian Gulf. Merlin and Ana cannot join as they have no travel permits. In other words, this will be Fujimaru's first journey alone with Mash in a while. But there sat the noble king, reciting a poem and cocking his head in contemplation. Having fun with tales of the past, Fujimaru and company's journey will finally become a lively one.
