The Kitten Project (Metal Bat Fanfic)

Miku Komatsu used to be your average 17 year old girl... That was until she was kidnapped by Dr. Genus and was tortured for his 'House Of Evolution.' He wanted to perfect human and animal extraction and evolution so he used little 13 year old Miku Komatsu to do so.
He did so many tests and tortured her to become his greatest experiment. He's tried on other girls before but they didn't survive...
The tests he did with Miku, left her so terrified and traumatized beyond comprehension.
She was locked in a cellar with other evolutionary animals to use against the Heroes.
Miku didn't want this, she would rather die than hurt a fly. Miku was a very sweet and shy child but after all this happened she grew to have a small temper.
After he used all his experiments on her, Miku was his first live and successful kitty project, and her code name is Kitten Project #10 because she was the first out of 10 girls to live...
She now has a long slim black tail with white tuff at the end, big black ears with grey tuff in them, her senses has been enhanced by 10 so she can see, smell and hear from miles away. She can run fast, climb high, her eyes glow in the dark and she has sharp claws and 4 sharp canine teeth.
After 4 long years of hell and going crazy trying to contain her animal side, she managed to escape by almost ripping off the doctors limbs and biting into his neck.
But now upon escaping, she had nowhere to go, until one day an old man by the name of Bang found her hiding in an alleyway in the freezing cold and decided to take her in...
She was confused but trusted him and told him everything. She now lives with him for the time being and couldn't be happier...but the trauma of her past hasn't left,
When Bang takes her to meet other heroes, she doesn't know how to react so she hides in the corner where it's normally dark and one of the Heroes decides to start drama...what happens then? Will he apologize? Will they fall in love?
