It is the 108th year of Volcano High School. In the classroom, chalk fly around like bullets. On the schoolyard, students and teachers hang in the air, competing against each other, using martial arts. At Volcano High, it is not surprising to see tea leaves moving in the shape of dragons or hallway windows shattering into bits with no one touching them. At Volcano High, the legend of the Secret Manuscript - the one who inherits these writings will rule the world - has been continuously passed down. From the outside, Volcano High School seems peaceful. However, a bitter showdown for the Secret Manuscript is at hand. Among the challengers are the assistant principal who thirsts for the principal's position; Song Hak-rim who became the best in the shortest time in the history of Volcano High; and JANG Ryang, captain of the weight lifting team who dreams of becoming the best at Volcano High.
