Lycoris to Aura
well we dont know why Aura is having kids, we need to wait for vol. 3 of the manga for that, but Lycoris IS an Experimental AI (read the books) she was part of Morganna's plan to make another Ultimate AI to create a loophole, Morganna did her job, technically, but Aura still hasnt been born, so Morganna wont be absorbed and die, but she realized there were problems with her loophole, so she just kept taking them apart, Lycoris is one example of an almost-Ultimate AI, she was about to become the UAI, but she got debugged and important files were scattered around the world, like her voice, her sight etc. and she made it so the one that debugged her couldnt log out (not like Tsukasa, he can walk around in the real world, he just can't turn off the game) so she follows him, and he collects her files and returns them to her, but Morganna tricks him and he ends up deleting her
