A young man from earth died from saving a child from being hit by a truck. Unfortunately he died in place of that child. He was then transmigrated into a different world without any cheat abilities by a god that went by the moniker, Author. This new world was one which he was quite familiar with. It was the Harry Potter Universe. Except... for some reason, everyone had access to the ability to level up and become stronger. This, is a new Magical World.
