Not gonna explain this au right now because I want to enjoy my break and make random doodles that I think of...
But some info you do get is that this AU is based on Mirai Park. If you decide to read Mirai Park, be aware of some gore. As well that the site I found it on is in spanish, however the pictures (aka what you read) are all in english, its just captioned in spanish.
