Midori seems to be the logical case as she is able to bring her illness into The World.
That has to be significant in some way, but I see your point as it should not be required to follow the story.
Yea, but the AIDA don't want anything to do with Midori at all, and infact avoid her. Midori's story has absolutely nothing to do with the main story with Unreturners, AIDA, Avatars, etc.
But Aura disappears before R:2 is created, so it must be more complicated than that.
No, it's not. She hid herself in the distributed Corbenic Epitaph, so that when the Corbenic PC-Body was made, CC Corp was totally unaware they put Aura in there.
It all seems kind of anticlimactic in the end. There are way to many loose ends. In the end what was the purpose of GU? To defeat Cubia and release Aura?
We've known the purpose of GU since the Terminal Disc was released. It was to bring back Aura, whether by forcing her back or by creating a new Ultimate AI to control the network.
An Unreturner and a AIDA-PC?
If she is an AIDA-PC and has such a strong AIDA then why doesn't she have schemes of her own?
Because AIDA don't make people evil. They just intensify emotions that are already there. For example, Bordeaux's rivalry with Haseo turning into hatred, Tenrawr's battle pride becoming bloodlust, etc. Aina only wanted to be with her brother. Not much for the AIDA to corrupt. Besides, they seemed to have been draining her thoughts and emotions instead of warping them, since her consciousness was corroding the entire time.
Is this infection rate from Ovan infected her or when Ovan was infected?
Huh?
Apparently Kite/Tri-Edge was not created by CCorp but was really created as a soldier by Aura.
What about Orca and Balmung? And the TSN?
I'm leaning more towards painfully obvious; before he was released from Ovan and took the form of a giant meteor he look and had all the exact same characteristics of an AIDA, which are way to many to be a coincidence.
Agreed, but I still want to know for sure.
I thought it wasn't that they wre strong AIDAs it was just she had a legion of AIDAs in her character, and my theory is that the AIDAs were much more interested in Sakaki infecting other players and becoming a demi-Morganna.
Correct.
