FAMILLY AU
You were running from your familly with him and some of your other siblings. They were not good people, really. They were bad and would do unspeakable things to you. But while you do that, everything was not going to be so easy, of course..
You two hid to somewhere, but then..A demon was to be seen, after a long fight, you two were bruised. He was more, to be honest. He fainted for a long time..
When he waked up, he found himself in the Butterfly Mansion. You and your other siblings sat next to him, with bandages on your face. They cried and hugged him. When he became better, the mansion trained you two, and put you two to the butterly siblings...
Now, you were inspecting your sword, and then, you saw him coming behind you, with a calm expression.
"Hey, what are you doing?"
