GunXSword opening theme

GunXSword, or perhaps more conventionally for English, Gun/Sword, is a mecha anime that is similar to Trigun in that it mixes science fiction elements with a setting resembling the American Old West.  It's the story of a man named Van who is wandering the world on a quest of vengeance, looking for the man who killed his wife.  His primary companion is a young girl named Wendy who is searching for her long-lost brother.  I usually tend to avoid the mecha genre, but so far I've seen the first 17 episodes and the giant robot fights have been held to a fair minimum and I've been enjoying it.

This is another anime in which a powerful hero (or anti-hero) character is accompanied by a much younger and relatively powerless companion.  This is a theme which is used fairly often, in my experience, for example it is also used in Claymore and Samurai Champloo.

Another similarity this show has with Trigun is that the opening theme is not an abbreviated version of a previously existing song.  This opening theme was composed specifically for GunXSword and is simply titled "GunXSword."  The graphics on this version are not great, but it's the only one I could find that wasn't just a slide show collection set to the theme music. Keeping in my that this story is western-themed, I think you should easily be able to hear where some of the inspiration for it came from. The composer is Kōtarō Nakagawa, who has created music for numerous anime and video games.
