World's Strongest Hunter Has No System

9 years ago Gates leading to parallel dimensions called dungeons appeared in random places around the world. Following suit is the existence of Diagrams, classes were given to 30% of humanity and with those classes are abilities you'd normally see in RPG games, each country had it's own Gate which must be cleared by hunters.

Among them was one person who aspired to become God from a very young age and always strived to be the best in everything he encounters, at first it was an impossible and completely futile dream and he soon gave up after he wasn't chosen as a hunter. But one morning, he wakes up to find that he was given the opportunity to become the world's greatest hunter in history.
