To start off, I wanna say a slight apology. As of right now, you all know of Sheik as this Kirito rip-off, but I want to make him more than that. So I brainstormed ideas to make Sheik his own unique character.
So, I made this story. Here, Sheik is a player killer who targets player exploiters, and Kirito is trying to help him break out of that murder spree. Just a note, this is a complete different world from the original SAO canon. There are differences between this world, and the original. You'll see this in the story in later chapters.
This is sudden, but I never gave Sheik an actual appearance, so here he is.
Yes, I know this is Jack the Ripper from Fate/Apocrypha. And I know this character is a girl. But this Jack the Ripper showed up in my Google search for anime traps, so...yeah. That's what Sheik looks like, white hair, short, green eyes. Just take out the scars.
Anyway, that's this introduction chapter, I hope you enjoy this backstory of Sheik. Love ya!
