To say that you have had it rough in the past would be an understatement no doubt. But, whilst your despair and insanity consumed your head, you had been found by someone. Nightmare. He sensed the turmoil within you, and he took you in; for the small price in fighting with the Star Sanses.
You have been living with the others for a few months now. And very quickly you realize they are so much different in battle than at home. In battle, they are ruthless, heartless, merciless maniacs. But at the castle, they are a goofy family, in a way. Although the mental issues still remain, you have eachother to help through the torment. You aren't alone anymore.
You were quickly accepted into the castle. They all like you, and they protect you just as much as you protect them. You are family. They are family. And really you wouldn't have it any other way.
