Darkness of Your Quirk [OneShot]

[Katsuki Bakugou x Reader]

You've once dated a boy in your middle school class. His name was Katsuki 'Kacchan' Bakugou. He was the sweetest person since the day he met you..or so you thought.

As you befriend a boy named Izuku 'Deku' Midoriya, you come to realize that your boyfriend is a heartless jerk who hurts on the one male with no quirk along side you. Stopping him, you announce that you no longer want anything to do with him; relationship related..

He was your enemy.

But, one day, you've put your life on the line just to save him..to save the memories when you see him. You still had feeling for him, but didn't show it. You let yourself get shallower by your darkness even more. When you save him, Izuku tried to save you as well since you were put in Katsuki's place, soon enough, your enemy tagged along.

When you saw both of them trying to save you, your quirk was unlocked. You had the newest, rarest quirk.. It was strong and dangerous to have.. It changed your human form entirely..

You had red pupils with the whiteness gone to black. Your hair somewhat changed into white snow. Wings, horns, teeth, and tails of a demon. Nails were painted pitch black and pure snow white. People started to call you Satan's Helper (or Fallen Angel).

When All Might saw you fight, re realize that you could control All for One.. So, he trained you and Izuku.

As time passed by since you unlocked your quirk, you and Izuku join UA together as a team and make it.. This only enraged your ex.

Now, you are a student of UA High School. You're in the top of your classes.. Only thing you have to do is contain your insanity; which was a mission impossible for you since you broke in a battle for the first time.

The darkness from your quirk gotten a hold of you..

Now, it was up to your ex and friend to help you out, and to find your way back into your old self..
