The most prominent case I can think of concerning an AI which made the transition from SAO to (new) ALO was Yui, and that was due to Kirito saving her file to his own NerveGear (and her going back there again near the end of the Fairy Dance arc).
But in the case of Pina, how was its data not lost when the original SAO self-destructed? Was the "backup" file used to create New Aincrad so detailed as to include that degree of granularity?
And from Silica's perspective, was she under the impression that Pina had "died" (again) during that interim period? Or has that not been addressed in any of the LN or manga material (such as Girls Ops)?
Yeah Nervegear has a hard memory like how Kirito saved Yui to his nervgear and his corrupted items were transferred over, similarly I assume that Pina's heart item would transfer over and since the beast tamer playstyle is availible then it would be possible to revive pina in ALO as well I'm assuming there would be a "revive" station for fallen familiars of beast tamers, since ALO isn't a cutthroat death game like SAO was. Well that's another way the author could have done it but whatever, very deus ex machina.
According to C9's logic, anything not written by the author himself is a fan fic. By that logic, both Girls Ops and the upcoming GGO novel are all fan fics since they weren't/won't be written by Reki himself. Can't you tell that I'm trying to contraargument? -_-
Actually, one thing I noted in the latest anime episode was Yui's note about the Cardinal System allowing player data, but not map data, to be stored in the event of a map reset.
Presumably that would tie in to what happened with Pina here - in that even though the original data for old Aincrad itself was deleted, the player info (to include avatars and items stored - such as Pina's feather) were in a recoverable condition?
Or to put it another way, the "copy" of the Aincrad castle itself that was used to build New Aincrad is kept apart from the recovered player data used to give SAO survivors their old avatars and items back?
