The NerveGear, the world’s first dedicated full-dive device developed by the genius programmer, Akihiko Kayaba in 2022…a revolutionary machine that opened up infinite possibilities for the world of VR (Virtual Reality). 4 years later…. A next-generation, wearable multi-device called the Augma has been released to compete with the NerveGear’s successor, the Amusphere. A cutting-edge machine boasting the ability to enhance AR (Augmented Reality) to the maximum, the Augma offers a safe, user-friendly experience, as it can be used while the player is awake, making it an instant hit. Its most popular title is an ARMMORPG developed exclusively for the Augma, “Ordinal Scale (a.k.a. OS).” Kirito is about to join Asuna and the others as an Ordinal Scale player, but they’re about to find out that it isn’t all fun and games… Source: crunchyroll
