Dungeons and monsters suddenly appear and the world falls into chaos. Ki-Bong Kim, an ordinary young part-timer, has been sucked up into an awakening dimension for 3000 years to train his powers. When he makes his return to reality, he is a max-leveled player who only has one wish -- to reconcile with his loved ones. 10 years have passed in the real world during his absence. How will Ki-Bong be able to find his place in the world with his new limit-breaking abilities?
