Yes I know some of the child theories and IF it is proved that Kuroyukihime is the daughter of Kazuto and Asuna, then I'll be one happy camper but I'd be happy even if they don't show such a relationship. The thing is that Kazuto does exist in the Accel World, since (spoiler) one villain mentioned his name.
