With all the battles in Underworld ended, all of this week’s SAO prior to the end credits takes place on Ocean Turtle, as Kikuoka, Rinko, Higa, and Nakanishi attempt to eject Alice (which is successful), log out Kirito and Asuna (who tells Rinko she’s staying with Kirito) and secure the facility.
Instead of the fantastical battles in the Underworld, it’s all metal, shadows, bullets, blood, and keyboard clacking. There’s more than a little Die Hard to the proceedings.
Gabriel Miller “wakes up” only to see his own body still lying dead on the STL, his face contorted in pure terror. He’s just a ghost, and Alicia appears and drags him under the water. When Critter reaches his and Vassagos STLs and finds them dead, he loses the will to fight any longer.
Still, his comrade Hans insists they continue their mission to the end. If they can’t steal Alice, they’ll destroy her by overloading Ocean Turtle’s reactor and rigging an explosive to cripple the control rods that prevent cataclysmic fission.
With Ocean Turtle suddenly converted into a ticking nuclear bomb, Nakanishi rushes to the reactor only to be pinned down by Hans, who is willing to die for Miller and the mission. He’s bailed out first by the robot Niemon, who somehow contains the consciousness of Kayaba Akihito, and also the wounded Kikuoka.
The deus ex machina Niemon is heavily damaged, but Akihito manages to restore control to the reactor and destroy the explosive detonator before collapsing, thus saving the Underworld, Alice, and his lover Rinko.
As Critter and the remainder of Miller’s team escapes on their sub, the timer zeros without any accompanying explosion, and Critter assumes they’ve failed. However, when he checks the bodies they brought with them, there are only two: Miller’s and Brigg’s.
What happened to Vassago’s? And what happened to Niemon, who also vanishes without a trace? We don’t know, and between those unknown elements, the looming JSDF, and Kikuoka’s health, the Ocean Turtle team can’t breathe easy despite no longer being in imminent peril.
Higa seems hopeful he can log Kirito and Asuna out before their fluctlights run out of memory capacity, but after the credits roll the two meet, embrace, and resign themselves to two hundred years in the Underworld.
No number of centuries matters to them as long as they’re together. And since they’re probably the two most powerful people in this “just born” new world, they feel obligated to do their part ensuring it will be a world of peace and happiness for all its inhabitants.
