One Eyed Devil

Chapter 1:Monster within

"Never trust anyone too much, remember the devil was once an angel."

Our story begins in an office with a shocked doctor and mother with a clueless black haired boy and green haired girl
Inko:"W-what did you say his quirk was?"
She said in fear
Doctor Garaki:"Ma'am it seems young Izuku had a genetic mutation due to his quirk, he'll never be able to eat normal food again he can only rely on human flesh for sustenance...."
As Inko looked at her son in fear
Inko:"He's a monster..."
She said to the doctor
Doctor Garaki:"Enough about him ma'am about your daughter she has a strength enhancing quirk as for Izuku use this quirk cancelling collar to prevent him from using his quirk"

Timeskip 9 years

Izuku had been put in the basement for the rest of his life tortured by Inko and Toshinori sent to school and beat up by Izumi and his whole class
Seconds
Minutes
Hours
Days
Weeks
Months went by as Izuku slowly started losing his grip on his sanity
He was hungry not eating human flesh had slowly started affecting him

Izuku Pov in the back of the classroom

In his mind

How long has it been since anyone has ever treated me like a human being
Every damn I'm persecuted cause of this accursed quirk

No it's not my fault that I'm treated like this

What's wrong is this damn worl-

Izuku pov out

Izuku had just been hit by an explosion knocking him out his thoughts as it hit his quirk dampening collar aswell

Katsuki:"Oi monster get a head start on killing yourself no one will miss you"
As he started beating him up as the class cheered,Izuku took one last glance at his girlfriend asking her to help him as she looked at him in disgust

Katsuki stopped beating Izuku up as  Izuku started fidgeting as he held his head in pain as some red tentacles sprouted from his back

Izuku:"AHHHHHH"
Everyone backed away from Izuku
Izumi:"What the hell,I thought his quirk was cancelle- Katsuki you idiot! You broke his damn collar"
She said shocking the class as they started screaming in terror,Izuku stood up And looked directly at his past friends
Izuku:"Could you do me a favour and shut the hell up for a second...."

The rest of the class could see Izuku's right eye had changed
Izumi:"I-izuku just calm down we can talk about this"
Izuku:"There is nothing to talk about,I've been treated as a monster my whole life so why should I not give into my urges as a monster does?"
He said as he brought forward his kagune

Izuku:"Now who to devour"

Izuku woke up from his dream in cold sweat,he was strapped to a chair from yesterdays torture

Izuku:"What the hell was that"
???:"It's the reality you could make possible if you just gave into your desires."
Izuku heard a voice in his head

Izuku:"Who tf are you?"
???:"It's simple,im the reason everyone sees you as monster the reason everyone hates you,I'm the mental manifestation of your quirk."
Izuku:"S-so your me?"
Izuku(Ghoul):"In a sense yes but enough about that,how long are you gonna let yourself be tortured by these assholes."
He said gripping Izuku's shoulder

Izuku(Ghoul):"Aren't you tired of the abuse,the neglect just say the word and I can end this for you all you have to do is accept me."

Izuku grimaced
Izuku:"Even if I'm treated like this it's better to be hurt than to hurt others...."
Izuku's ghoul side smirked in annoyance
Izuku(Ghoul):"You really are a fool."
As he disappeared leaving Izuku alone in the basement
