대타용사
Facing annihilation at the hands of the Demon King, a distant world starts pulling champions across dimensional lines to fight on its behalf. The spell that reaches Earth grabs Song Yi-seok, a thoroughly unremarkable salaryman who happens to be a namesake of South Korea's most celebrated martial artist, and everyone on the other side assumes the legend has arrived. Now hailed as the savior he definitely is not, he has to bring down the Demon King while keeping his total lack of talent under wraps.
