Sword Art Online (ソードアート・オンライン)
The NerveGear's revolutionary virtual reality plunges thousands into Aincrad, a sprawling medieval realm where players can explore without limits,until the game's creator seals them inside. Escape demands conquering one hundred perilous levels, but death in the game means death in reality. Kazuto "Kirito" Kirigaya, a beta-tester, discovers his head start offers little protection against insurmountable bosses and ruthless conspirators. Alongside Asuna Yuuki and fellow skilled players, he fights to lead everyone to freedom before the nightmare consumes them all.
