Saw this post on tumblr: my-friend-the-frog. tumblr post/ 57492013658/ reversal-demonstuck and so I just had to write a fic to go with it

Prologue:

Derse was a dangerous place to live. It wasn't the crime rate - that was relatively low. It wasn't the nuclear power plant - which was abandoned two-thirds of the way through building. And it wasn't the extensive stray dog population - there was never a problem with rabies. No, what made Derse such a dangerous place to live was the fact that it was a gate town. And the gate it protected was Prospit. Prospit was the largest pit in Skaia, and was even used as a full time lock down for some of the most dangerous demons out there.

Now, demons aren't inherently evil. But every time both moons were full (every 35 days) they went berserk. The horror terrors that normally kept them pacified would stop whispering in their ears and they would be left with only one instinct: hunt. And that is why gate towns existed.

Every thirty-five days, the demons living there would be forced down into the underground cities to live out the full moons. Breakouts during this time were rare, but they still happened. That's why every human in the gate town was taught to fight. Because, if it came down to it, they would need to kill their best friends to save their own lives.

One such breakout happened in Derse. And unlike normal, the horror terrors didn't return once the day was done. They stayed gone for two weeks. Ten human children faced off against their some of their best friends during those two weeks, and neither side made it out completely unscathed.
