Anyways, I watched a couple episodes of Gunsmith Cats, and it's pretty entertaining, I know I saw an omnibus of the manga at a book store, so I might have to get it.
A couple of episodes is about all they did. Unless something came out that I missed the only Anime they did was a three episode mini-series in the early/mid nineties. Which sucks because for a long time it was my favorite manga. But if you liked the Gunsmith Cats anime make every effort to get your hands on the Riding Bean anime. It's a single episode pilot for a series that got caught in legal hell and never went anywhere but it's AMAZING. It's also the predecessor to Gunsmith Cats and the creator re-used a lot of the same characters.
Bean Bandit is the fucking man.
