Kadokawa’s Dengeki Bunko will publish a prologue chapter, but they are keeping major story details under wraps. Kawahara did tease that the arc’s title is a mathematical term like Ordinal Scale, but the two stories will not be linked together.
This will be the first new story for Sword Art Online. All previous story arcs, except for the Ordinal Scale movie, were based on Kawahara’s original web novel versions. Alicization served as the web novel’s finale and is receiving an anime adaptation.
Kadokawa will also reveal more information about the Alicization anime the same day they publish the prologue to Unital Ring.
