Thank you for the thread!
What I have posted on here of Demon Story doesn't fully show the world it primarily takes place in--although you get a small taste of it in the prologue.
The world that Demon Story mainly takes place in is a world ruled by demons--who are only called that by humans who fear them, in actuality they are just long-lived beings who have both an animal and human form, and supernatural powers that relate to their specific animal. Demon and human society have clashed for millennia, an almost instinctual hatred running between the two groups. And yet, within the storm of hate, sometimes seeds of love can bloom and the product of that are the half-demons who occupy the lowest wrung of the societal ladder. Demons subjugate them cruelly, humans use and abuse them, elves typically ignore their existence. Being a half-demon isn't just hard, it's nearly impossible to live in a world that's so cruelly stacked against you.
But many half-demons persist even in the face of hate and discrimination.
Half-demons, btw, are unique beings for many reasons. The first reason is that from the time they're born until they hit puberty, they look like and for all intents and purposes ARE normal humans. But when puberty hits, it causes a change in their body make-up and their demon blood "wakes up", bringing with it a variety of changes that vary from half-demon to half-demon, even amongst ones that share the same kind of demon. Most will have their ears altered into a reflection of their demon side's ears, but some will have tails, wings, or other animal traits develop either instead of or alongside the typical ears change. Some changes are advantageous, but many at first can be crippling. Every half-demon experiences their changes differently. They also typically have powers and abilities that, while related to their demon side, are completely different from those that demons have.
"Wait okay but you mentioned elves?!"
Ah yes, elves are in this story too but due to various reasons that are plot-related, they are a species on the brink of extinction with a society full of its own problems and conflicts with demons and humans both. You learn about them eventually.
What I have up so far on here is only the beginning portion of the novel itself, but I've also written various side stories involving characters who appear later on that showcase these aspects of the world. You can find them here on my AO3.
