High noon. A tumbleweed rolls through the deserted street. The saloon doors burst open - it's time to duel. But the West isn't like what it used to be. Virginia's dueling pistols rust unused, as this callow youth is cheatin' slime, bringing his curiously ineffective holy machinegun. Two can play that game, though. If Jet wants to up the ante with a rapid-fire weapon, Nana will be unleashing the deadly might of her electric Yo-yo. This duel is going to be simple: mano-a-mano gun-yo combat with neither mercy nor remorse. And Nana, with the superior weapon, will win. Cuz' in the Wild West, you don't mess with the yo-yo - not even with a machinegun.
