Sword Art Online anime producer Kazuma Miki reassured fans that Sword Art Online: Alicization will cover the entirety of Alicization light novel arc. However, Miki didn’t hint at a potential episode count while speaking the fan event.
The Alicization arc comprises of 9 light novel volumes, which is longer than previous Sword Art Online arcs. It follows Kirito waking up in a new world called Underworld, which is an advanced virtual location. With no past memories, Kirito learns to survive with help from A.I. “people” as he tries to uncover the mystery of Underworld.
A-1 Pictures will return to produce the animation and Yoshitsugu Matsuoka will reprise his role as Kirito. There is no release window for Alicization, but Sword Art Online fans will have Sword Art Online Alternative: Gun Gale Online to hold them over starting in April.
