A young girl sits, crying, on a bed, similar to that of a prisoner's bed. Her back and nails bleed as a few of her previous feathers lay on the floor. Her mentor ripped out the glorious wings and her claws once more for the purpose of strengthening them. Her claws he removed so she didn't look villainous. It has been this way since she was 5 they would rip her wings and claws out and speed their growth up only to repeat the process. She learned pretty quick to cut her hair short so she wouldn't get blood in it. The kid across from her looks terrified as they watch her blood flow from her back and nail beds. Her mentor was careless this time. They didn't heal her like they should have and throwing her in the cell room reopened her wounds. She stays seated crying silently until she passes out from blood loss. Six years old and she is living a nightmare.
Waking up once more she sees her mentor holding the bucket where he had thrown the water and got up to follow him, preferring not to be beaten along with her wings and nails removed again. They left her wings and claws to grow back slower this time due to the pain it brings. An excruciating pain of wing bones and claws ripping out of her flesh and growing. Her eyes hold little emotion and her body looks barely the size of a four year old as she barely eats due to the pain. She has tried to escape several times and is beginning to believe her quirk is not only manipulation of her red feathers but of immortality though she knows that is impossible. Another setting with old blood stains remaining, she braces herself against the wall as her wings are slowly broken before being ripped slowly from her body.
~Small time skip~
Sitting up in cold sweat she hangs her head, her back burning from the tug at her muscles. Now 14 she waits for the perfect time to escape just wanting to be free. Her wings are spoofed and covered in blood as 2 long feathers are hidden under the shirt of her back cutting into her back slightly in effort to hold them there. The gates opened. SLICE. His head came off clean, coating the girl's pretty feathers with blood red rather than the crimson they are. She ran,her wings still hurting after growing still not fully in, she ran. Heads rolled from whoever she passed as she sliced them off clean. She didn't stop. She reached the gate outside and flew up, unstable like, and used her advantage to leap over the gate. She continued to run till she couldnt no more, where she crawled into a little cavern type thing made by the critters of the forest, between an Oak tree's roots. Falling asleep to the cries of the creatures around her.
