Sword Art Online is about a new virtual reality game that offers players a completely immersive experience.
However, what starts as a fun adventure quickly turns into a deadly trap when the game's creator locks thousands of players inside, making it impossible to log out.
The only way to escape the game and return to the real world is to conquer all one hundred levels of Aincrad, a dangerous medieval world.
If a player dies in the game, they also die in real life, raising the stakes considerably.
The story follows Kirito, a former beta tester, as he teams up with Asuna and other players to overcome the challenges of Aincrad and fight for their survival.
They face difficult bosses and other obstacles in their quest to beat the game and return home.
