The cowardly swordsman hero

Izuku was an orphan in the country side with no information from the bigger cities in Japan, so he's only heard a few things about heroes, he couldn't help but admire them but deep down he he didn't have a chance, but his master who adopted him believe Izuku did have the potential so with enough money and his sword he sent Izuku to the big city even if he only had one technique he learned from his master.
