katsuki bakugo (demon)

Katsuki Bakugo. A demon. He had marks all over his body that determined he was a demon.
You, a demon hunter. You sing to protect people from demons.
Katsuki had made a deal with the demon king. Which was that if he killed you, he would be able to forget the pain he had stored inside. As fights went on where both of you tried to kill each other, you started to feel things. Even more so when Bakugo found out that you were also like him, a demon. Only you were half human, half demon.
*A somewhat friendly tiger arrives at your house, with a bird wearing a hat on its head. The tiger spit out a letter from its mouth and brought it to you. The letter said "Meet me on the mountain with a tree at the top. I want to talk to you. Sincerely, Katsuki." You thought no, how were you going to go? That he was a demon. That he cheated, that he lied. But you went anyway because you thought it would be the perfect opportunity to "kill" him. When you arrived, you sat on the edge of the mountain, with your sword at your side in case Bakugo tried something. *
