Weak Hero

Due to widespread bullying in Eunjang High School, weak students live in constant fear of becoming the next prey. But their luck is bound to change when Gray Yeon—a scrawny freshman, no taller than 157 cm—leaves the entire class in shock—stands up to a bully twice his size and overpowers him with ease. Gray's courageous act, resourcefulness, and unique insight earn him the nickname Eunjang's White Mamba. Despite his size, Gray continues trading blows with bigger and stronger bullies from other high schools in town, all in hopes of preventing history from repeating itself.

Once the bullies target you, it’s game over. The school is run by tyrants whose favorite hobby is tormenting the weakest kids in class. But then Gray arrived. This mysterious new student threatens to dismantle the established order. He may be small in stature, but his calculative and brutal fighting leaves unsuspecting opponents lying on the floor begging for mercy. Now the school's toughest bullies have to scramble to take down this new and unusual hero.
