Izuku Midoriya's POV:

The day I got my quirk was the day my life changed forever. From being mocked and bullied to abused, beaten and so much more, every day for something I never did. The day after my quirk manifested was the worst, my dark green hair was now pure black like the night sky. The colour of green eyes changed into a deep red colour just like of a ruby. I also grew some kind of appendages, a black tail with a bit of fur at the end of it and two black long horns with some shade of dark crimson red on top of my head.

Just because my appearance changed that didn't meant my personality also changed, but people only saw me as a monster or a misfit in their eyes. They would also call me names such as 'Devil's Child', 'Satan's Son', 'Demon', 'Freak Show' and many more. It also didn't help because my mother started to abuse and neglect me after my new appearance. But this whole thing showed me something, people are cruel to those that have mutation quirks, the society is unfair and most of all was that nobody cared for me... until one day. Everything changed when I met her that day, the first person to show me kindness after years of torture, my beloved Mistress.

I was eight years old when I met her, I was thrown out by my so called 'Mother' because she had enough of my appearance and I started walking away from the place called home. It has been a few days since I was thrown out of my old home and it has been difficult to live outside on my own. I stopped going to school two weeks ago after I couldn't handle the abuse, the name callings and the people would just ignore me like I didn't existed. I was walking through the park that I used to play with my mother before my transformation, I was wearing a black hoodie and gray pants with my red shoes, but then I heard a girl's scream. I headed to the sound of the scream. Normally I try to avoid people to not get too much attention but this time it felt like I needed to do something. Maybe it was my own selfishness or just trying to be some kind of a hero, but I didn't care at that moment. When I got there, what I saw made my blood boiled, three kids bullying a small black haired girl with a spiky ponytail in a white dress and shoes with her back towards the big old oak tree, and they were preparing to attack her using their quirks. Just when I was about to interfere between them I heard one of them talking cruel things about the poor girl.

???: "You can't become hero with a useless quirk like yours! A hero needs a strong and powerful quirk like mine!"

The blonde kid started doing some kinds of explosions in his hands. The black haired girl started to talk back stuttering, still feeling scared of the situation she was in and also trembling quite a bit.

???: "P-please... I-I d-didn't do anything w-wrong..."

Just then, one of the other boys told the blonde boy something, which only added more fuel to my anger and the fire inside of me.

???: "Hey Katsuki, isn't she in our territory, we should teach her a good lesson to not mess with us."

Katsuki: "SHUT UP! Don't order me around, but you're right. We should teach her a lesson to not mess with us. Isn't that right guys?"

The other two boys only responded with a smirk on their faces. The little girl in white dress still scared was backing away slowly from them hitting the tree with her back. At that moment I knew I had to do something, I always wanted to protect and help people. Even though my appearance changed on the outside, I was still me inside. I was always pushed away and have been lonely since I was little. Still, I just couldn't leave them to beat her up. Then I started to walk faster towards them and shouted to get their attention. All of them stopped and looked towards me, even the small girl.
