The Scent Of Rain And Fear

Naelen was born with fangs in her mouth and a wolf beneath her skin. Her quirk, Animal Within, makes her something most people fear-sharp nails, a predator's instincts, and a quiet connection to the dark that never leaves her side. Driven from a home that never saw her as human, Naelen survives in the alleys and shadows until a tired, sharp-eyed Pro Hero crosses her path and does something no one else has: he doesn't flinch. Aizawa finds her on a midnight patrol, and for the first time, Naelen is offered something other than a cage or a command: a choice.

But wolves don't trust easy. And the path out of survival is slower than anyone expects.

A My Hero Academia fanfic, learning that darkness doesn't always mean danger.
