In the final night of rest everyone will get before the decisive battle with Tiamat, Gilgamesh warns Ritsuka and Mash not to blame themselves for Uruks fall, or dare pity the city or its people, but to stand proud of the amazing works they have achieved. That humanity is still here at all is all down to Ritsuka forming the new goddess alliance.
Quetzelcoatl seeks refuge at the Chaldean Embassy, not wanting to upset the cityfolk who considered her a fearsome enemy. She reveals to Ritsuka that she knew Gorgon and Tiamat were seperate entities ahead of time, but couldn’t tell the truth lest Ritsuka or others come to pity Gorgon.
Ishtar and Mash have a nice one-on-one, looking up at the stars of those who came before them, lived, shined, and died. Mash still fears battle, but because she has so many things she cares about and doesn’t want to lose. Leonidas once told her that heart of hers would be an invincible shield as long as that heart doesn’t break from the strain.
Finally, Gilgamesh meets Kingu atop the ziggurat, and has neither hatred nor pity for the one who stole his best friend’s body, which Gil heals using a grail from his treasury. Gil regards Kingu’s current position as an enviable one: his own free will is there to pick up and take. Kingu seems to take that to heart when he shows up for Gil’s final rally to his warriors of Uruk.
With that, Ritsuka, Mash, Ishtar and Quetzalcoatl head towards the rapidly advancing Tiamat, only hours away from a surely doomed Uruk. While en route they hit a cloud of lahmu and a resurrected Dark Ushiwakamaru, who is determined to stop them in their tracks before they do the same to her “Mother.”
Yet it is ultimately Ushiwaka who is stopped, and by her own former subordinate Benkei, returning to make up for the wrongs of his lord. As with her last appearance, there isn’t the slightest hint that Ushi could ever come back from her dark transformation, but Benkei isn’t looking to save her, but give her an honorable death, ending her suffering and anger for good.
He achieves this by holding Ushiwakamaru and her shadow clones in place as the wake of Kuku’s booming Noble Phantasm, Piedra del Sol, washes over them. Ushiwaka and Benkei’s Spirit Origins disappear, but while Tiamat is briefly stopped, she sheds her legs and starts to float above the sea of flame, despite being an earth goddess.
Since the plan was to drag her down into the underworld, the fact she is now airborne jeopardizes everything. Kuku doesn’t stand still, but takes advantage of Tiamat’s pause to throw everything she’s got left at her. Ritsuka fortifies Kuku’s Magical Energy, allowing her to unleash Ultimo Tope: Patada, in an increasingly awesome avant-garde display of destruction.
Essentially transforming herself into a comet (like the one that struck the Yucatan peninsula and decimated the dinosaurs), Kuku is able to destroy a number of Tiamat’s barriers, but once the dust clears, there’s no sign of Kuku remaining—we saw her very flesh cracking and shedding as the launched her attack—but Tiamat is still intact.
The Chaldeans’ options continue to dwindle as Tiamat keeps throwing wrenches into their carefully-laid plans, but it is not over yet. Kuku’s attack left a wound at which they can still scratch. Ishtar is still on the board. Ereshkigal’s underworld is still below if they can only manage to bring Tiamat back down to earth. Finally, the now-healed free agent Kingu still looms on the sidelines. I can’t imagine he’ll stay there.
