Also Kurohime got a deeper 'need' to met the creator of the game than the usual player, like it's something written in her subconscious. Still if it was to hide that her name was Kirigaya or Yuki, this would make sense. In the usual case we would have been exposed Kuroyuki's real name and if we wanted to hide her relation to a X character we would hide that X character's name. My basis for suspecting this is the following: There is no reason to hide Kuroyuki's name except to hide her being related to a character the viewer knows. The second case is not interesting enough to explore it here so I'll go with the first case. There's actually two ways I could see it: -Kuroyuki is Yui -Kuroyuki is Kirito's and Asuna's real daughter. Kuroyuki is or is related to Yui/Asuna/Kirito Now we'll enter in some deeper speculation. We also know that part of his reason for doing that is for his 'daughter' Yui. 20+ years after SAO has been over, it wouldn't be weird for Kirito to have made a name for himself in the field. Kirito also show interest in the VR development and it also seem like it'll be what he's planning to do with his life. Also the safety limitation was known only to an handful of people, including Asuna and very likely Kirito once the project is over, limitation which is respected with BB. Now would it be really a stretch to say that Kirito (One of the few people to ever have tested the technology with his own body) could have gotten hand of it after the Alicization project has been finished? I don't think so. This suggest that the Alicization project didn't turn out well, that this technology wasn't approved of and that the project got scrapped. Note, that system could go up to roughly 3000+ times but was limited to 1000 times when human used it for safety purpose.

Still roughly 20 years earlier, RATH already completed the acceleration system which they used in their Alicization project. In AW's setting, 'accelerating' is definitively nothing normal, to the point where Hariyuku was shocked to the thought of it even being possible. While we do not know the reason why Kirito would have created BB, if he did create it then these points would pretty much support his character. Those three points give off a 'Kirito feel'. BB have minimal influence IRL, memories that could create big turmoil are even erased at the same time as the program. BB is a game where your 'complex' form your avatar, basically it gives you a chance to face and come in term with yourself, to overcome yourself. BB is a game with no scenario of life and death, something people can truly compete against each other for the fun of it. Okay so I am going to for the most part copy and paste this theory!! Kirito is the creator of Brain Bust. So, I looked up on Google (#notspon) 'Sword Art Online conspiracy theory'. Okay so I just saw MatPat's Fullmetal Alchemist theory and I was really disappointed that SAO didn't win the vote.
