The world of SAO was created for two reasons.. One;For hardcore gamer's two;For someone live once more... Akihiko Kayaba had a younger brother who died,with the horrible pain of losing his brother he created an A.i that acted just like him,looked like and even sounded like him...The new M/n was perfect...however the body made to hold this A.I wasn't going to be ready for another year..so why not make a game for him to live in and communicate with others...More like trap them and make Thousand of players stay with M/n forever. Warning;Bad grammar!!! So don't judge me???
