As the Incarnation of Sin, I Play With the World by Negative Energy

Special arms Wilson, who had retired from military service, accidentally got a mysterious scroll. After signing the contract on the scroll, Wilson got a capability! He could improve his strength by collecting negative energy! Sex, abuse, fear and killing could all be the source of his strength! From then on, he became the incarnation of sin! The city with him was a symbol of danger. Countless women were raped and killed by him in all kinds of environments at midnight, and the city fell into a panic. Relying on the negative energy provided by these things, he gradually had a terrible speed and strength. Even when the negative energy reached a level, he began to possess the supernatural power! Wilson gradually ruled over all the underground forces and became the king of the dark world. Did Justice want to judge me? Impossible!
