In modern day Japan there lives two rival gangs: Spurious and Kosher.

The Kosher gang demands justice while Spurious demands freedom. While these two gangs are causing a ruckus, there is a lonesome boy caught up in all of it. It's you! A total loser who is deathly afraid of thugs. But perhaps you can overcome your fear? Maybe you can even ... fall in love?! Or get punched a lot accompanied by a voice grumbling "MRGRGR."
