Ritsuka and his Servants attack Tiamat directly, and Isthar is seemingly able to destroy her with her ultimate attack. However, Tiamat then reveals her true, gargantuan form. Realizing they have no way to fight Tiamat, Ritsuka and his servants retreat back to Uruk. Meanwhile, the black mud overflows onto the shore and is only held back by Uruk’s defenses. Upon returning to Uruk, Ritsuka is dismayed to find out that the black mud has wiped out all of the surrounding cities, leaving only 500 survivors within Uruk. Furthermore, Roman points out that since Tiamat is the primordial goddess that gave birth to all life on Earth, she has no concept of death and cannot be killed as long as life on Earth still exists. Ritsuka suddenly gets the idea of sending Tiamat to the Underworld. Since there are no living things in the Underworld, Tiamat should be weakened enough to be killed. The group concludes that they need to halt Tiamat’s advance towards Uruk for at least one day to give Ereshkigal enough time to set up a gate to the Underworld underneath Uruk. Gilgamesh then asks Ishtar to use the Bull of Heaven, Gugalanna, to battle Tiamat. However, Ishtar admits that she has lost Gugalanna and had been searching for it ever since she was summoned. With no solid plan delay Tiamat, Gilgamesh orders everybody to rest for the night.
