A small underground mafia group called Bangtan. They commit the crimes, go off the radar, and repeat. After they rob a bank, one of the members say that they should leave their mark when they commit a crime. Bang. The thing is, is that it was a bad idea because a girl saw them write their new catchphrase before they left. Too bad she is too smart to let them get to her.
