Sword Art Online: Re:Aincrad

In 2022, a new virtual reality game called Sword Art Online launches, utilizing NerveGear technology to provide a fully immersive experience by stimulating the brain. Players soon realize they cannot log out, as the game lacks a standard exit function. Trapped in the game's world known as Aincrad, players are told they must complete all one hundred floors to escape. Failure to do so results in death, both within the game and in the real world.
