Asuna Yuuki had never played online games until accidentally putting on the NerveGear for Sword Art Online, the world’s first VRMMORPG. She soon finds herself and other players trapped inside a game, where if a player dies in the game, they die in the real world. As she continues to live on in this world where death is always a step away, a solitary swordsman named Kirito appears before her.
