My Martial Arts Fantasy Academia

The world of Martial Arts and Job Class....

It was the world where dog eat dog was normal. He entered the academy and did an awakening ritual. But to MC's surprise, he was not able to awaken. After that, Renji was deemed as the weakest as he failed his awakening. The world looked down upon him and treated him as trash. But he face slapped everyone with his Martial Arts!

He will defeat everyone with his Martial arts as his goal. With that, his story of becoming the strongest will unfold. Would he last with just using martial arts in a Class dominated academy? Or not?
