I was an orphan, without any family ties. I was adopted by a mysterious organization and forced to learn how to kill. My life was numb and I chose to commit suicide.
When I opened my eyes again, I became a baby. My new parents loved me so much that my cold heart gradually melted. When I was 10 years old, the Blood Cross came in and killed my parents.
During my escape, the old man from the valley rescued me and trained me. From then on, I embarked on the road of revenge against the Blood Cross Society for my parents.
