Sword Art Online is a light novel series written by Reki Kawahara and illustrated by abec, who also is the author of Accel World.

The Sword Art Online anime aired in July and was produced by A-1 Pictures, which received a large reception; it was followed by a recap film, a second season, and an original anime film that released in over 1000 screens worldwide. Since then, the series has appeared on a plethora of media with international merchandise, various manga adaptations of the light novel’s arcs, and video games. In addition, Kawahara has relaunched the series as Sword Art Online: Progressive, a re-release of the light novels with additional content.

Here is a synopsis of the anime from MAL:

1 year after the SAO incident, Kirito is approached by Seijiro Kikuoka from Japan’s Ministry of Internal Affairs and Communications Department “VR Division” with a rather peculiar request.

That was an investigation on the “Death Gun” incident that occurred in the gun and steel filled VRMMO called Gun Gale Online (GGO). “Players who are shot by a mysterious avatar with a jet black gun lose their lives even in the real world…” Failing to turn down Kikuoka’s bizarre request, Kirito logs in to GGO even though he is not completely convinced that the virtual world could physically affect the real world.

Kirito wanders in an unfamiliar world in order to gain any clues about the “Death Gun.” Then, a female sniper named Sinon who owns a gigantic “Hecate II” rifle extends Kirito a helping hand. With Sinon’s help, Kirito decides to enter the “Bullet of Bullets,” a large tournament to choose the most powerful gunner within the realm of GGO, in hopes to become the target of the “Death Gun” and make direct contact with the mysterious avatar.


Part 2 of the anime’s third season, Sword Art Online: Alicization – War of Underworld, airs every Sunday at midnight on Tokyo MX. It will run for a total of 23 episodes.
