Sword Art Online: Alicization

Kikuoka explains to Asuna and Rinko that Kirito's brain was severely damaged from the attack and they are using the STL technology to restore it. He also reveals that the main focus of the Underworld experiment is to create a new, more advanced form of artificial intelligence. Despite the experiment having proven successful, they note that by establishing the Church of Axiom inside Underworld, the AIs have managed to completely eliminate all kind of transgressions, including murder, from their community, and that they needed someone with years of experience in VRMMORPGs like Kirito to interact with them to develop them further. Asuna deduces that Kikuoka's objective is to create AIs capable of murder for military purposes, and he confesses that all of his actions since the development of the NerveGear was created for the sake of this research, labeled "Project Alicization". After checking on Kirito and informing her friends, Asuna is approached by Rinko, who formally apologizes for helping Kayaba during the SAO incident. Asuna replies that, while Kayaba can't be forgiven, she is thankful for the days she spent with Kirito inside Aincrad.
