"God of High School" is an all-styles martial arts tournament for high schoolers from all over Korea. Jin Mori, who lives on his own after parting ways with his grandfather Taejin at a young age, is on his way to the preliminary for his region when he ends up chasing a snatcher. In the midst of his pursuit, he meets Han Daewi and Yoo Mira, two other high schoolers on their way to participate in the preliminary. The only thing on the line is your pride! The only thing you can trust is your fists! Choose any wish, and it will be granted! Such is the power of God! So begins the battle royal featuring the most powerful contenders from all over…

Mori, Daewi, and Mirahave made it through the first preliminary round. With the next round coming up, the three of them talk about their reasons for entering the tournament. Mira says she’s hoping to find a strong man who can become the successor to her late father’s Moon Light Sword Style and rebuild her family’s dojo. On the day of the tournament, one of the favorites to win the tournament, Gang Manseok, faces off against tai chi user Go Gamdo.

In the first match of the national tournament, Mori loses his team’s opening bout by applying a pressure point he learned from Bongchim of The Six, which renders him immobile. The second bout pits Daewi the tournament’s oldest competitor, 38-year-old Jin Pumgwang, who overwhelms Daewi with powerful attacks acquired through years of hard physical labor. Meanwhile, Commissioner Q is attacked by Drake, a member of Nox, and seriously injured. Q ends up removing his limiter so he can call upon the power of the gods, and the charyeok Joker materializes!

When he learns of Nox's existence and their role in Jin Taejin's confinement, Mori swears to win the tournament and save him. But his opponent, Ilpyo, also has a good reason why he can't afford to lose. Four years ago, Seungah's sister and Ilpyo's cousin, Seungyeon, had her leg broken by Jegal and had to give up martial arts for good, and Ilpyo has made up his mind to become cold-hearted for her sake. Meanwhile, Feilong, whose attack on Mori failed, is eliminated... as Jegal wears a cruel smile.
