“Ugh… This is horrible…” He grumbled to himself. How on earth did he get himself into this situation? All he wanted to do was spend a bit of his free time volunteering for a charitable organization and was even excited at the prospect to work with some kids, but he never imagined it would be like this.

He continued to clean up the mess on the floor and the stench of goblin blood was permeating his senses making him nauseous. He needed to finish this quick before he puked everywhere and had another mess to clean up.

Turns out, this was no ordinary charity, it was a place where parents of vampire, or werewolf or oni or any of the “good” species sent their children to learn and play when they would not blend well in a typically normal human school. These species were no mystery to the people of the world and when the rift happened that brought them in or changed existing humans into one happened 5 years ago it seemed like the world would be soaked in a bloodbath. But very quickly normal humans and the “good” species formed an alliance as the rift also brought about “bad” species like goblins, trolls, and the mindless undead.

This was one of the first organizations to form to teach these new kids all the same stuff we had been teaching kids before the rift, but with added curriculum of using their powers appropriately and slaying the “bad” creatures. And from time to time a goblin or some other smaller one would make its way onto the grounds and the kids would just have a hayday.
