The 2nd season follows the same characters we all love. The 3rd series is wonderful also and well worth checking out.
A year has passed since SAO was cleared. Summoned by Seijirou Kikuoka of the Virtual Division at the Ministry of Internal Affairs and Communications, Kazuto (Kirito) learns of a series of bizarre murders linked to the popular VR game, Gun Gale Online (GGO). After being shot in-game by a player calling himself Death Gun, two prominent GGO players have mysteriously turned up dead in the real world. As Kazuto logs in GGO and starts investigating the mystery, he meets a girl sniper named Sinon who wields a Hecate II rifle. Is she friend or foe? Kirito enters the virtual world once more for an all new adventure!
Im speechless. Truly the best show ever created.
Personally I love Sao and can't wait for season 3. If anyone is wondering when season comes out, I did some research and found out that it isn't due till ATLEAST 2017, which is disappointing D:
You should watch it.
