Ep. 1: Death Gun shoots a player in Gun Gale Online, prompting Kirito to investigate real-world deaths linked to the game.
Approximately one year after the Sword Art Online incident, the VRMMORPG Gun Gale Online becomes popular in Japan. During a stream, a figure named Death Gun shoots at the avatar of top player XeXeeD, causing him to disconnect violently. A month later, Kazuto Kirigaya meets Kikuoka Seijiro from the Ministry of Internal Affairs' Virtual Division. Kikuoka reveals that XeXeeD died of acute heart failure shortly after the incident and presents evidence of a similar death involving another Gun Gale Online user. Despite Kazuto's skepticism that a game can cause heart failure, Kikuoka suspects Death Gun targets professional players and asks Kazuto to resume his Kirito identity to investigate. While Kazuto considers this request while spending time with Asuna at the park, the sniper Sinon remains in peak condition within Gun Gale Online.
