That one guy looked like Spike from "Cowboy Bebop". It even had a style like "Cowboy Bebop".
I haven't even watched much of that show. This was so well animated. I even loved the author's comments. It is pretty different than what I've seen here before.
I wish this was part of a series. Then again, it's so awesome, it doesn't even need more installments. The violence was so creative. You just had no idea what kinds of weapons would be used and where. The dialogue was hilarious too. It just hit every note perfectly.
