KO One: Max-Level Vajra Demon Subduing from the Start

Su Yi unexpectedly transmigrates into the world of The Ultimate Series.

From the start, he is bound to a Brawler Combat System.

And so, a man's figure begins appearing with increasing frequency at the gates of various high schools.

At every school he visits, all the top fighters on the KO Rankings get an inexplicable beating.

No pattern, no reason, no mercy, and nowhere to hide.

Before long, he earns the title of High School Killer.

Just as Su Yi is still caught up in the process of getting stronger,

Bala High School extends an olive branch to him.

And so, he officially becomes a teacher at Bala High School.

"Those guys from Banana High are picking a fight? Brothers, let's go kick their asses!"

"What? The teacher already took them all down by himself?"

"There's no problem a good fight can't solve."

"And if there is, beat them up again!"
