Fujino seemed to write that the Aincrad arch was completely canonical, so Asuna and Kirito got to Aincrad in 2022, stayed there for 2 years. Then the deviations begin. Asuna ended up in ALFheim, captured by Oberon, and for some reason Kirito did not go to play it, so he did not save Asuna and is not familiar with Lyfa. It turns out that Asuna was held captive by Oberon for a year or more, until her father saved her and erased her memory of those events. Further, as far as I can understand, Asuna and Kirito just lived up to the current time on 7/04/2026, went to school and played FOG, a game that was completely invented by Fujino. Kirito didn't play GGO in Fujino's universe, so Sinon doesn't know, and it's not clear where Silica disappeared to, because both Asuna and Kirito met her in Aincrad and Silica was supposed to play ALFheim. It's also unclear what Kirito was doing instead of saving Asuna. Was he treated for psychological trauma after Aincrad?
