Plot synopsis:
In an alternate universe, many people are addicted to Avalon, a military-themed virtual reality shooter. In the game, solo players or parties raid levels populated with AI-controlled enemies and opposing players. Winners are rewarded with experience point and in-game money, which can be exchanged for cash, allowing skilled players to make a living. As their brains interact with the game directly, Avalon places significant mental strains on players, and has rendered players catatonic in many cases.
Ash is a famously skilled player, who only plays solo after her party Team Wizard was disbanded. After a Class A mission, the GM (Game Master) warns her of the next level's danger, and suggests she joins a party. The next day, Ash watches a Bishop-class character break her record time on the same mission. Intrigued, Ash tries but fails to learn about him or his avatar. As she leaves the game terminal, the Bishop player watches her.
Ash runs into a former teammate, Stunner, who mentions Murphy, her former team leader. As the two visit Murphy at a hospital, Stunner tells her Murphy went after a hidden NPC in Avalon, a young girl nicknamed "ghost". The girl is allegedly the only gateway into the rumored Special A, an extremely rewarding but incredibly challenging mission where players cannot "reset" (a mechanic allowing players to abort mission without their avatars being killed). Players who went after "ghost" never wake up from the game and became "Unreturned". As Ash walks through the corridor, a girl looking similar to "ghost" watches her. Ash looks at Murphy, who has now become comatose.
At home, Ash searches for words regarding Avalon, Unreturned, and the ghost. The search leads her to the "Nine Sisters", another Arthurian legend reference. Further researching and questioning the GM proves fruitless. Upon entering the game, Ash receives an invitation to a meeting, and is ambushed by a group of griefers, who lured her there to rob her equipment. After she overpowers a player, the group leader reveals that only the real Nine Sisters - Avalon's creators - know how to access Special A. They are interrupted by an attack helicopter which kills most of the players. Due to a lag, the helicopter's missiles teleport in front of Ash. She "resets" and leaves the game, narrowly avoiding losing her avatar. On the way home, Ash notices people around her are immobile, with the exception of a dog. At home, after she finishes preparing a meal for her dog, she realizes that it has disappeared. She hears the helicopter from the game flying pass.
The next day, Stunner meets Ash. He tells her of a high-level Bishop player who can make the ghost appear, and is sought out by parties seeking to enter Special A. Before becoming an Unreturned, Murphy himself was a Bishop player. At her house, Ash finds the Bishop player waiting. He offers to form a party with her and she accepts. Ash arrives at the game terminal and tells the receptionist that she plans to enter Special A to look for Murphy. She enters the game, despite warnings from the receptionist and the GM.
In the game, Ash meets the Bishop player, whom she suspects is working for the Nine Sisters. Stunner arrives, revealing he has been helping Bishop recruit Ash all along. The party confronts the Citadel, an enormous boss. Stunner, Bishop and his summoned dummy players distract the giant, while Ash attacks its weak point. After the Citadel is destroyed, Stunner spots the ghost. He is then shot by an enemy. Before being forced out of the game, Stunner tells Ash of the only way to kill the ghost. Ash goes after the ghost and manages to kill it, turning it into a gateway. Ash steps into the gateway and disappears.
Ash "wakes up" from the game booth, which is put in her apartment, wearing civilian clothing and without equipment. Bishop contacts her and tells her she is in Class Real. The only way to exit the game is to complete the objective: defeat the Unreturned staying here. Ash takes the provided gun and proceeds to her destination, an Avalon-themed concert by the Warsaw Philharmonic Orchestra. On the way, she is stunned by the vibrant and bustling world, which is in stark contrast to the previous levels and to the world outside the game. At the concert hall, Ash sees Murphy, and they walk outside to talk. As she confronts Murphy about his decision to stay in the game, he states he prefers the "reality" within Avalon. Ash mortally wounds Murphy, who urges her to stay, then disappears. Ash enters the now empty concert hall, and sees the ghost on the stage. Ash trains her gun on the ghost, who flashes a smile. The text "Welcome to Avalon" is blended in.
