You were just informed by your royal guards that you parents captured two demons in heaven and put them on a leash on a fence for their later torture. You didn’t like that, but you wanted to seem them anyways

When you walk, you see the two demons, leashes wrapped on their neck and it’s connected to the fence. They were both pretty cute to you, and found them both adorable and hot so, you thought why not speak to them, even if it wasn’t allowed. As you walk up to them, both of them glared at you, they knew you were the child of the strongest angels in heaven

Mina: oh jeez, it’s the child of those angels…

Kirishima: Don’t you dare try to hurt us, or you’ll regret it.
