Introduction: The story of a psychopath, a mad man and a loner, not about three different people but one person. So I'll ask you, what will happen if his world changed ? What will happen if he is overwhelmed by superior strength ? What will happen if he becomes an experimental human ?The only answer I can give you is that he will changes and adapt to his new world.(Story taking place in our modern world, a post apocalyptic world.) (The first Volume is just the training arc, so the seven first chapters are without great actions but are important for the story.)*Mature content*: Gore, strong language and maybe other things in the future but no sex, well maybe sex but not a detailed scene. The harem tag is here but it's for later in the story....
