The Night-Sky Blade
Along with Asuna, Alice heads to the World’s End Altar, the console for ejecting Fluctlights. To buy them enough time to reach it, Kirito confronts Gabriel, who’s become the incarnation of pitch-black nothingness. Unless he can defeat Gabriel and make it back to the real world before the maximum-acceleration phase begins, Kirito will have to spend the next 200 years in the Underworld. Trying to stay calm, he crosses swords with Gabriel, who’s taken on a peculiar form.
