Ruling The World As The Mighty Hero

This is a tale about a man acquiring the power he does not deserve. After a life of suffering and tragedies, and then ultimately dying in the hands of the people he despised the most, the spiteful soul didn't rise to the heavens or burn in hell. Instead, He woke up inside the body of a righteous hero in another world. Engrossed in the power that he now holds, he swore to assume the identity of The Hero Alsten. However, the title alone will never change the pathetic scum that he is, inside. Instead of living his life as the hero by slaying the demon king and saving the world, he did whatever he pleased. Through violence, he got whatever he wanted. He used his powers to rule humanity according to his ideologies—his selfish desires. But who can stop him? He's the almighty Hero Alsten. He was invincible. Nothing in this world will ever hurt him again. "Everything is mine. I will do whatever the fuck I want." "Why should I show you mercy? The world can spit on my face but I'm supposed to save it? Fuck that." "Bow down to me or die. Sing my praise or don't talk at all." "Nothing else but my satisfaction matters. This world is mine to devour. This time, the world is my slave."
