The Sixth Child

In 2003, 5 children were murdered in a Chuck-E-Cheese like restaurant. What people didn't know was that there was a sixth child that had survived the culling. Now grown up, he comes back to finish the case that was never completed...

(This is obviously based on the FNAF world. Just think of it as an alternate world where Afton was never found to be the killer of the 5 children. It's also placed forward in time for the technology to be right for the protagonist to use and where the children were actually found, not put behind a secret room in the FNAF 1 map. I won't be changing the fact that Afton died in FNAF:SL though, you will find out why in the later Chapters/Nights.)
