A year has passed since the events of Sword Art Online (Season 1), Kazuto Kirigaya (Username: "Kirito") is living peacefully back in the real world with Asuna Yuuki (Username: "Asuna"). However, he is recruited by Kikuoka Seijiro of the Ministry of Internal Affairs' Virtual Division to investigate in a new series of killing in a Virtual Reality MMORPG game called "Gun Gale Online". The player named "Death Gun" is suspected for already causing the deaths of two GGO players via shooting their avatars in the game, somehow coincidentally causing their real body to suffer an acute heart attack. Can Kazuto reveal the secret link that leads to death via the Virtual World, or will he himself become a victim to the judgement player "Death Gun"?
