Hero the Maximum

Gang-Chi Han is a failed student who couldn’t excel in any field. His GPA hits the bottom, ranking last among his classmates. His skills, whether it is soccer or computer games, are scorned by his peers. Whatever he does, he doesn’t seem to do well. But he lately comes to a realization that his punching power is out of this world. With a little help from his father, the Handsome Bum, he enters the First Branch of Heroes. Now, the villains must shiver under his might, but will they?
