Mashle: Magic and Muscles is a Japanese manga series written and illustrated by Hajime Komoto.
The series follows Mash, a young boy who lacks magic but is the strongest person around. He is born into a world of magicians with magic marks on their faces, and is forced to attend a magic school to become the best magician. Despite his lack of magical abilities, Mash’s advanced physical strength and determination make him a unique and powerful individual. Many say that this series was heavily inspired by Harry Potter, and the protagonist being compared to Saitama from One Punch Man.
A mashling is someone who is very easy to belittle or punch, a easy mashling is someone who is very easy to hate, while a hard mashling is someone who is hard to hate but easy to beat up.
I swear to god, that guy over there is a easy mashling, I really want to punch the crap out of him.
Dude, don’t fight him, your a easy mashling he’ll beat you to sleep.
