The war between the two cities continued and a protracted conspiracy took place. I was forced to be separated from my family since birth and became an experimental subject. From then on, I was unable to have any emotions. I thought this was my destiny. After the truth was stripped away, I realized that the person who raised me and taught me was a pervert who lived to kill. And if I want to change this world and put a bottom line for all malice, then I will become the devil himself. From now on, I will guard the gate of hell.
Concept: Every era needs bad guys with a bottom line
