The world is cruel. The world is unfair. Those with wealth and power possess the globe. Then, they trample on others’ back and do whatever they want to do. This happens in my world. When I was young, my parents were killed in fire catastrophe in our apartment building. All I could bear in mind was a mysterious man saved me that night when I fainted. He trained me well with his fighting skill and raised me to be an assassin. One day, I was offered to work with a secret agency. What I could say, they paid me more. Highest bidders won. So, I served them. I left the old man to pursue new career. When I was 25, titanium was injected into my body. They took out my soul and I became a cold and merciless killer with no sense of humanity in my heart. Human with a devil soul. That was me. It was proven by all the successful tasks that I had accomplished throughout my career.
