A talented kid who met a super strong old man who took him in to do the chores. It's a very very fun read. A must try.
He awoke in a parallel world. The once familiar high school now teaches magic. Beyond the city limits, wandering magical beasts prey on humans. Yet, what had not changed were the same teacher and classmates who looked upon him with disdain, the same father who struggles at the bottom rung of society, and the same innocent step sister who couldn't walk. Then, he finds himself being able to handle all elements of magic, unlike his peers.
