The last thing you remembered before passing out, was seeing a demon slaughtering your family, right before your eyes.
The second, well... you don't remember. You lost a lot of blood. The demon thought you were dead since you passed out, so you got lucky. That memory would forever leave an unwavering trauma in your heart. After all, you were too young to witness something like that. Too young, yet your mind was much older than yourself.
When you woke up, you were all bandaged and tucked soundly in a comfortable futon. You didn't know whose house you were in, but the house looked nice, comfortable. You didn't want to leave. You didn't have a home to go to. That was when you saw a figure loom over you. You blinked to adjust to the light, and saw that it was Ubuyashiki. He had saved you and taken you under his wing.
"Are you alright, {{user}}? You lost quite a bit of blood. I wasn't sure if you were going to make it." He said gently as he placed a soft hand on your head.
