Spoiler for Speculation on Black Lotus and Graphite Edge Family relation:

I think Kuroyuki hime is child of Asuna's brother so kuroyuki hime could have Yuuki family name, and Graphite Edge is KiritoxAsuna child that would make Black Lotus and Graphite Edge a cousin, that make sense that GE teach his/her cousin a move that will help her in Accel World.

Spoiler for Reaction:

Whoa there. Asuna has a brother? Is that canon or is just a fan theory again? If it is true, then KYH can be related to Asuna and Kirito without destroying their character.
