No Export for You: Much like Ginga: Nagareboshi Gin, the manga has yet to receive a full English translation. Though that doesn't stop most fans from reading the Japanese pages and more or less understand what's going on as action takes up a lot more of the story than talking.
The manga briefly had an official English translation, known as Ginga Legend Weed. It didn't last very long, though.
The anime actually was going to get dubbed with the creator of Feral Heart voicing Weed and GB having a slight British accent. Some of the scenes of the dub were up on YouTube but were taken down after the production got cancelled after the company went bankrupt.
