The World's Greatest Martial Arts Instructor

Synopsis

Ha Mubaek, the master who annihilated both the Demon Cult and the Blood Cult, ends up being sent as an instructor to a martial arts training institution due to a clash of power struggles. He probably thought he could hide his identity and live a quiet life this way, but it seems his reputation is creating chaos. His mission? Solve the issues of students prone to exploding in fits of anger, educate the trashy Water Dragon Academy, and yet... things are getting strangely chaotic...? What's this? A genius lunatic instructor is a first, right?! (Source: Kakao Entertainment Corp., translated)
