Trigun: Badlands Rumble

In town surrounded by quicksand, an outlaw from Vash the Stampede's past has resurfaced after twenty years. His name is Gasback - and he's looking to cause a little trouble. It seems Gasback has a serious beef with the town's mayor, who's paying dozens of bounty hunters to protect his turf. One of those hired guns is a beautiful woman with a vendetta against Gasback. Will she get a shot at revenge? Maybe, if she can get through Gasback's bodyguard, Wolfwood. And what's Vash got to do with this mess? Nothing much - except for the fact that he personally set off the entire chain of events two decades ago! (Source: Funimation)
