"I'm Not A Nephilim,Cambion,Angel Nor A Demon. I Don't Know What I Am Actually"

Aviva fern Rowen Winchester,Daughter of John and Mary Winchester,Sister to Dean and Sam Winchester.

Aviva didn't look too different from her family but she had her unique quirks like sometimes her eyes would glow faintly when she was in certain moods.She knew she was unusual but she knew none of her family were normal,they hunted monsters for a living.

What nobody knew was she is a Angel-Demon hybrid,she was mostly angel but nobody knew that. All Mary and John knew was she's their adopted daughter whom was left at their doorstep.
