Gangryong is a high schooler; unlike others, he has always had a dream of being the strongest. One day he meets Youcheon, who teaches him a powerful skill. One year later, people come to see him and announce that his 'master' is dead. Because he was his only student, Gangryong has to follow them and go to a school where everybody has supernatural powers.
The new English teacher, Chun-Woo, is not your ordinary teacher. Shioon, a victim of constant bullying, unexpectedly witnesses Chun-Woo`s fighting power, and begs him to make him his disciple.
