Hiding in my stomach where no one can find her is a beast.
She's a shapeshifter, this monster. Sometimes her skin is leathery and membranous, and wings stretch where her arms used to be.
Sometimes she's a mass of fur and horns and talons. Sometimes she's just a fog of darkness leaking into the world.
But she never lets me forget that she's there. When I look into the mirror, I see her. I'll touch my face and find it utterly human, and yet my reflection is a leviathan. A demon. She used to terrify me, make me sweat and shake from fear.
But I've come to accept that this is what I am. A monster whose teeth are stained with blood of mine and others. I can never brush them clean.
