Akihiko Kayaba was many things. A genius, an innovator, a madman, etc... Unfortunately for the various pantheons, he wasn't exactly "Human" either, and by extension, neither were some of the beings who got stuck in SAO. What will the aftermath of the SAO incident be like with the supernatural thrown into the mix? Only time will tell. Inspired by Punitor567's "Devils of Aincrad"

When rifts connecting two worlds form, chaos tends to follow suit. How will the people of Remnant deal with the supernatural? How will the Pantheons of Earth deal with the creatures of Grimm? How will a certain someone feel about dealing with the parents that killed him and his sisters? Those first two are a mystery, but suffice it to say that Duncan Renatus isn't happy about this.
