I'm Trapped by Power

I am a person cursed by power, with the ability to kill anything instantly with one punch. This is a world where monsters are raging, but fortunately, there are heroes who are fighting on the front line to silently protect this world. I am incompatible with this world. Because of the influence of power, I find that my emotions are almost zero. It seems that nothing can affect me. No, I want to get back what I have lost!
