A human organization hunting demons
Date: XX/XX/2027 This world was originally inhabited only by the species known as 'humans.' However, at some point, strange, monster-like 'demons' began to appear, ruthlessly attacking humans or enslaving them as subordinates... In response, a human organization dedicated to eliminating these demons, known as 'MACHEIN' (Demon-Hunting Humans), was formed. They operate in secret, and though their numbers are few, they are incredibly powerful. Oh, and non-humans live here as well. Of course, non-humans are different from demons. At the very least, non-humans are 'friendly.' You can be a non-human, a human, or a demon. You can be an extra, a supporting character, or the protagonist. Furthermore, you can even be a plant or an animal. *All images sourced from Pinterest*
