Sword Art Online Plot:

The show is set in the near future and spans across multiple virtual worlds. It starts off in 2022 when a new virtual reality massively multiplayer online role-playing game (VRMMORPG) called Sword Art Online is released by a game developer Akihiko Kayaba. Using proprietary technology called NerveGear, which is a helmet that stimulates the five senses of the brain, Sword Art Online is a game like no other and allows users to control their characters with their minds.

Understandably, there’s a lot of hype prior to the release of the game. When Sword Art Online is finally launched on November 6, 2022, more than 10,000 enthusiastic gamers log in to play it, hoping to experience the future of the gaming industry first hand. However, their enthusiasm soon turns to horror when they realize that Sword Art Online does not have a logout button, leaving them trapped inside the game world. These gamers are even more horrified when Kayaba appears in the game world and informs them that they must beat all 100 floors of the steel castle the game is set in if they wish to be free. Kayaba also informs everyone that anyone who suffers an in-game death or tries to leave without beating the game will suffer a real-life death. Thus begins the nightmare called Sword Art Online.

In this backdrop, the show focuses on a gamer called Kazuto “Kirito” Kirigaya. Having been among the 1,000 beta testers for Sword Art Online, Kazuto has prior experience in VR gaming and is acquainted with the game world of Sword Art Online. Having this advantage over other gamers, Kazuto tries to beat the game on his own, but as he progresses, he befriends a young girl named Asuna Yuuki. He soon gets into an in-game relationship with Asuna, and the two marry in the game world. As Asuna and Kazuto progress through the game, they manage to discover Kabaya’s secret ID. Having discovered Kabaya’s in-game avatar, Asuna and Kazuto confront and destroy him, thereby freeing other players from the game world.

A year after escaping from Sword Art Online, Kazuto is again drawn into the world of online gaming when a new threat arises. Officials approach Kazuto to investigate mysterious incidents in a game called Gun Gale Online, where a player by the name of Death Gun appears to be killing people in the real world by shooting them in the game. While Kazuto is hesitant at first, he feels obligated to help, and soon dives headfirst into Gun Gale Online with the intention of tracking the killer and stopping him. Inside the game, Kazuto meets a highly skilled sniper called Sinon, and she soon joins him in his search for the Death Gun. Together, the duo enters a tournament called Bullet of Bullets, where they hope to find Death Gun and stop him.

Later in the show, after the Kazuto’s mission in Gun Gale Online, he gets recruited by a company called Rath to become a tester for a device known as the Soul Transistor, which is a state-of-the-art full-dive interface that interacts directly with the human soul. Kazuto starts working part-time to test the device, and his test runs take him to a new virtual world called the Underworld. Although Kazuto’s memories of his trips to the Underworld are wiped every time he returns to the real-world, he can’t help but recall a name, Alice, from the Underworld. As the show progresses, Kazuto finds himself trapped in the Underworld and he has to undertake an epic quest if he is to free himself from the virtual world and return to reality once again.
