Actually, Sugu is not really friends with Kirito until late ALO, so if she had entered SAO, they would probally not meet eachother until late in the game (reason for so, Kirito is extremely unsocial with people, and the two first people he talked to were Klein and Asuna), meaning she might die until such point.
