Summary For the Alicization arc
Kirito awakens in a vast, fantastical forest filled with towering trees. In his search for clues to the truth of his surroundings, he encounters a young boy who seems to know him. He ought to be a simple NPC, but the depth of his emotions seem no different than a human. As they search for the boy's parents, Kirito finds a peculiar memory returning to him. A memory from his own childhood, of this boy and a girl, too, with golden hair, and a name he should have never forgotten—Alice.
The Dengeki Bunko Fall Festival 2017 event also announced the Gun Gale Online novel series by Keiichi Sigsawa will be receiving a new anime projected titled Sword Art Online Alternative Gun Gale Online.
