One minute Kirito is pushing Asuna away from the injector in a lunging Johnny Black’s hand, the next, he’s waking up in what he soon surmises to be the Underworld, neither the real world or a game, but a virtual world. After the dense, somewhat whiplash-inducing first episode, it’s nice to have a simpler, more elemental outing, in which the protagonist is just as much in the dark as we are.
Kirito soon meets Eugeo, and learn that six years have passed since Alice was arrested and taken away by the Axiom Church for her transgression. Since then Eugeo has kept hacking at the Gigas Cedar. Clearly Kirito doesn’t remember being friends with Eugeo, but he gets vague, nostalgic glimpses of Alice, and he and Eugeo hit it off in short order when he offers to do some of the axe work.
Eugeo explains the Stacia Window interface everyone has, along with the concept of callings, the extent of his in particular (over 300 years and seven generations), and the Taboo Index that keeps him from searching for Alice but also prevents theft.
In the village, a kid named Zink who mocks Eugeo’s job as “useless” is put in his place when Kirito “thinks he remembers” his calling was that of a swordsman. To Kirito’s surprise, going through his usual SAO/ALO/GGO motions results in unleashing a powerful sword skill.
Kirito spends the night in a church, where his schedule is dictated by the head sister, and uses the time before falling asleep to think things over. He posits that all of the “characters” he’s encountered could be copies of the souls of newborns raised entirely within the Underworld, making them “Artificial Fluctlights.”
With at least 300 years having passed in this world (and possibly many more than that), Kirito worries what the ramifications would be of living for months, years, or decades in the Underworld while in the real world mere hours or days are passing.
His ultimate goal is to contact Kikuoka, which he believes might be achievable in a larger city like the Central City Eugeo mentions as the place where Alice could still be alive. Before heading there (where a powerful-looking woman lounges atop an ornate tower), he resolves to learn more about this world (you clearly do not want to break any laws here) and properly preparing for such a journey.
