Creators: Based on a light novel series written by Reki Kawahara and illustrated by abec.
Basic Premise: Nerve Gear is a new tech that allows MMO players to engage in a "full dive," experiencing a virtual world as if it were real in every way, and feeling as if they were just as present there as in the physical universe. On the release of the "Sword Art Online" fantasy MMO, thousands of players sign up and log in – only to find that they cannot log out again. If they die in game, their bodies will die in the real world as well (talk about permadeath). If anyone on the outside tries to disconnect them from the system, their bodies die as well. The only way to escape alive is to clear the game.
