Nanbaka x Female reader

This story is where the reader is a girl who was experimented on by her father, a demon named Shi Akuma (death demon), she holds a secret that only the warden and supervisors know about.
She joins cell 13 in building 13 and meets the boys for the first time!
I have provided a picture of what your character could look like but anything that is red on her can be your fav colour instead and the skin tone can be different! More details will be provided in the first chapter!

PLEASE NOTE:
This is my first story so please don't judge! Yeah I know I am late into the fandom but I don't care!
