Well, Second Chance turned into a crossover suddenly.
More pictures and a synopsis can be found here: [link]
This is based on my Second Chance timeline, which is based on the Trigun Maximum manga. That's why Vash's hair is black. If you haven't read the manga (you poor thing!), I highly suggest you do so. The anime is a candle to the sun in comparison to the manga. The anime was good, but it's simply outclassed by its source material. The original wins, in this case.
Vincent Valentine leads a confused Vash the Stampede and Nicholas D. Wolfwood out of the Forgotten City after he found them while investigating the strange energy spike caused by their arrival. Getting ambushed by Vlakorados certainly isn't high on Vincent's list of favorite pastimes, but the encounter just beyond Bone Village is a good chance for him to learn about these newcomers through observation. Cid dropped Vincent off in the area, and they are on their way to meet him. From there, they will head for Edge. Vincent normally wouldn't waste energy on random strangers, but he can sense that something about Vash is distinctly OFF.
