Yokou sighed. Well, he would have to explain eventually, anyway. Might as well get it over with. "Alright. Might as well tell you now- it's only fair, after all. You'd have found out sooner or later. Just...try not to freak out too much." He said, leaning against the carriage. He didn't want to sit up next to her, in case she did freak out. "It's a strange story. It started when I was just a kid, back when my family was still alive. See, the mansion I live in used to belong to my parents. It was always full and busy, since my parents had four children. Two girls and two boys. Then there were the servants...anyway, everything was pretty good. I was the youngest of the four siblings, by three years. As a child, I was always very social. I was sickly and weak, though, so I couldn't play with the others like I wanted. I was lonely..." He shook his head. "That's no excuse. But I was lonely. And over the course of my life, though my siblings all seemed fine with me, my parents were so distant and cold. The one thing I wanted, more than anything in the world, was for my parents to love me. Unfortunately, this was never to be. It all started one night, when I was only ten years old. I was feeling better than usual, and I was playing hide-and-seek with my siblings. While I was hiding, I overheard my parents talking. I'll spare you the details, but the basics were that my father wanted to get rid of me. And my mother...she said she had wanted to drown me at birth. A "useless, sickly whelp." That's what she called me. I thought it couldn't get any worse, until my oldest brother and sister- they were twins- walked in. Father asked if they had managed to find me yet, and they said no. As it turned out, they were all scheming to kill me. They wanted to get me to hide outside, and then just leave me, so that I would freeze to death and it would look like an accident. The only one not in on it was my sister, who was three years older than me. She was always kind to me...anyway, I never was a stable child. I had...issues. Hearing that exchange must have...I don't know...broken something. Sent me over the edge. I ran to the kitchen and found some matches and kerosene. I waited until everyone was asleep, then doused the floors with kerosene and lit a match. I intended to burn with the rest of the family, but my sister found me sitting in my room. She tried to get me out, but...the fire blocked the door. She got burned badly. I cried, realizing that the one person who ever really loved me would die. A that moment, time froze. I don't mean figuratively, I mean the flames stopped in their tracks, nothing moved, time literally stopped. A great, terrible beast rose out of the flames and smiled at me. I will never forget that smile. It was horrible. The beast offered me a deal. My body in exchange for my sister's life. Desperate, I accepted. The beast flew into me, merged with my soul. With it's power, I was able to get my sister out of the house. I watched the mansion burn all night. It died down just before dawn. At dawn, my sister woke. She took one look at me and seemed to know what I had done. She wouldn't speak to me. For two days, she stayed silent, until the day I came back with some berries I found, and found my sister laying on the ground, dead. She simply gave up on living, and died of a broken heart. The beast within me had saved her from the fire, only to let her die days later. I buried her, then started to rebuild the mansion. After that, I lived alone, researching demons and possession, learning to control the creature that dwells in me to this day. Recently I couldn't bear the loneliness anymore, and decided that I had enough control to be around humans. That's when I went to buy you. Every once in a while, the demon's power leaks through, which is what happened just now. You can go ahead and either freak out or call me insane now." He finished, glancing up at her to see her reaction.
