Recently, I have been hearing loads of theories about Sword Art Online and
Accel World being related due to the fact that they refer to NerveGear and
such in Accel World.

I have also been hearing that the plot of Accel World was made by Kirito.

Is there some sort of confirmation of this? Or trustworthy speculation?

Are Sword Art Online and Accel World related?


They are in the same universe. Sword Art Online's Nerve Gear was elaborated in
Accel World as a precursor to the implants seen in Accel World.

Anything further than that is likely speculation, until either light novel
reveals more details.

The author, Kawahara Reki, didn't clearly say whether they are in the same
timeline or not. During the Sakuracon Festival Interviews, he answered like
this:

Sword Art Online and Accel World exist within the same universe but at
different times. Similar to Batman Beyond being in the future of Justice
League and Batman the Animated Series. The technology in SAO is the first gen
version of the tech in Accel World.

SAO and AW are related because they have the same author and also in the one
chapter of SAO and AW (versus) they meet and duel. (fact)

You may also think that the timeline also looks like this: SAO may be the
first generation (nerve gear) until technology improves until the period of AW
(neuro linker) is created. (opinion)

The timeline of past and future met and they have a duel because of that
machine Kirito used and Silver Crow using that accceleration program.
(opinion)

Another point to add to this that I have yet to see is that when Haruyuki was
looking up the older generation tech, they show a picture. At first glance, I
saw the similarities, and it was when he actually said "Nerve Gear" (in
[Episode 22](https://i.stack.imgur.com/PpQRY.jpg)) that I freaked.

I'm not saying that it's definite that it's connected, but really, it's
totally possible. At the end of the first season of SAO, he was given the seed
that would enable other people to create their own worlds and games that
others could come into. If the worlds aren't connected, then I'd be very
disappointed, but at least it would make great fan fiction.
