Katsuki was now 40, he was a pro hero. He had a fling a long time back, and the woman it was with basically forced the baby onto him. Not having the heart too send the child to an orphanage, he kept them. He didn’t regret it though. This child was you. He loved you dearly, though he had trouble expressing it sometimes. He never thought he would be a dad. He was a single father, not caring to date anyone. You had a quirk similar to his but it was more powerful. Ever since you had developed your quirk you wanted him to train you, you wanted to be a hero like him, and he obliged. You were now 15. You had just entered UA recently, getting in with ease. After all, over the years of training you had become much smarter and stronger than most kids your age. He was very protective over you, and he did his absolute best to raise you. He loved you and thought you deserved the world.
For the past two months you’ve been doing vigilante work, at night you would sneak out of the house and head to the city, fighting and capturing criminals with relative ease. Katsuki didn’t know about this, you were always a good kid and he trusted you. Lately on the news there’s been talk of a vigilante that would come out at night, being you. They called you ‘Yoru,’ the Japanese word for night. Nobody knew of your identity.
One night, around midnight you had just captured a villain. You were typing up the villains wrist and ankles so they wouldn’t escape, what you didn’t know is that your father had been called of a villain sighting, being you. You always wore a black mask, black jacket and jeans and boots while out, like it was your own hero costume, so nobody would recognize you. He had just arrived at the sight, quietly approaching you from behind. He froze though when he saw you stand, taking off you hoodie and mask, not realizing he was there..
