In the world of the Mafia, there are three sides. The protagonists; Super Junior, Seventeen, U-KISS, and Twice are the good guys. The enemies; IKON and SNSD are the bad guys. There’s a third side however that no one knows-the ones who pretend to be on one side but is in the opposite(in this case bad are actually good); BTOB and Winner. There are also 5 types of rolls: Leader, CoLeader, Tech Geek(s), the weapon intelligence, and the combat(fists and feet) In order to not get killed, all groups do minor tasks...until now.
