Hareluya Hibino is a rebellious young man who loves to get into fights. Since his father is God, and he does not approve of Hareluya's rebellious behavior, he decides to send him to earth to begin his 1st year at Rakuen High School. From that moment, Hareluya will have in mind to do a lot of things to achieve a goal, which he calls: to conquer the world.
