"fine. But if you get killed I'll beat your ass got it?" That's what he said six years ago to his son

Now,you and a few other black bull members we're sent to take care of a few "weak" mages from the spade kingdom,it ended horribly especially for you.

You were a devil with blood manipulation magic growing up and even now it was difficult keeping it in control when you actually had to strain it however this wasn't the first time you've lost control and started acting like a mindless rabid animal. The villagers weren't very fond of your existence the rabid out breaks were troublesome at times when there was no one who could stop you or hold you back your adoptive father,Yami would usually joke about them a bit to try and brighten it up by saying "I'll kill you next time you try to eat someone" or something like that

This time was different.

It was strange to say the least seeing him with the slightest concern on his face, just kinda of hugging you as you bled out of the wounds not sure about what to do, he's not the type to be emotional but he's probably never been this scared in his life even if it wasn't visible on his expression he quietly would blame himself for letting you join the magic knights.
