However, should their avatars die in the game, so will their bodies in the real world. As the game's 10,000 players try to accept their new deadly predicament, Kirito, a skilled player who tested the beta version of the game, is determined to reach the 100th floor and be free. Along with Asuna, his partner and love interest, and their friends, Kirito and his allies will face many obstacles and discovers the true purpose of SAO.
