Hero's Carnage

Lucas is a homeless teenager who had everything taken away from him— his family, his home, his childhood. Even worse, he was born without any abilities in a world where humans with superpowers dominate.
All of that would change when a new dungeon appears before Lucas.
Thinking that it was a sign the gods have given him— that he should just give up and end himself, Lucas enters this dungeon without hesitation while expecting death.
However, inside the dungeon was not the end like Lucas had expected.
Instead, it was the beginning of his life of carnage.
Wielding the power of a 'Hero', Lucas begins his journey of vengeance on the world that stole everything from him.
