Recording (a youtuber fanfiction)

Sierra has been living life normally for as long as she can remember; nothing really interesting ever happens in her small town.

But one day, everything seems to turn around. While she's in school, there's a mysterious lockdown. Unfortunately, Sierra is outside of the classroom, and none of the doors are opening. Desperate for a place to hide, Sierra darts into a closet, to which the door is opened soon by...Bijuu Mike? As Sierra comes out, she realises that she's surrounded by YouTubers that she recognises, but even THEY didn't really know each other. Bijuu Mike, Inquisitor master, and Thinknoodles, as well as others in the same room??? Sierra has to pinch herself over and over again to make herself believe she isn't dreaming.

she soon is told that the reason for the sudden lockdown is the fact that there has been a mysterious outbreak of strange monsters, such as Slender Man, Zombies, and for some reason horror game antagonists, including Baldi and Monika!!!

as weird as the situation is, Sierra agrees to go with the YouTubers to track down the cause of the sudden outbreak...could it possibly have to do with any of them?

They were the chosen few out of the millions of YouTubers, so...what gives?
