Yun Si-U is a master of the fighting game "Bloodfist”. Even in real life, he can see a system that usually appears while playing games. Feeling bored with the game, Si-U turns towards actual combat, and tries to use his abilities to conquer his school, but is defeated by the snow leopard Hong Min-Jae. In order to compete with him again, Si-U joins the martial arts club "Lalapalooza"…
