Kazuki Hoshino values his everyday life above all else. He spends the days carefree with his friends at school, until the uneventful bliss suddenly comes to a halt with the transfer of the aloof beauty Aya Otonashi into his class and her cold, dramatic statement to him immediately upon arrival:

"I'm here to break you. This is the 13,118th time I've transferred. After so many occasions, I have to say that this is all starting to grate on me, which is why this time I'm spicing things up with a proper declaration of war."

And with those puzzling words, the ordinary days that Kazuki loved so dearly become a cycle of turmoil and fear—Aya's sudden appearance signals the unraveling of unseen mysteries surrounding Kazuki's seemingly normal friends, including the discovery of mysterious devices known as "boxes."

Yi "Shioon" Shi-Woon's everyday life at Nine Dragons High School—which consists of beatings from fellow student Ho Chang and his gang—is far from ideal. But one day, a mysterious man named Han Chun Woo spots one of these beatings and instead of offering support, brands Shioon a coward for refusing to fight back, adding insult to injury. To Shioon's surprise, he finds out that Chun Woo is the new substitute English teacher at his school.

Tired of the daily abuse, Shioon decides to enroll at a martial arts academy to learn how to defend himself. On the way there, he stumbles upon Chun Woo in a predicament—cornered in an alley by a group of angry men! Provoked, Chun Woo suddenly dispatches them using martial arts techniques, which Shioon covertly records. Later, he uses this recording to blackmail Chun Woo into teaching him to defend himself. Reluctantly, Chun Woo agrees, and Shioon is soon thrust into the world of martial arts, known as Murim. However, Shioon is naive and unaware of his master's shady past and the unseen underbelly of society. How will Chun Woo manage to teach Shioon and help him survive in the world of Murim?
