Rui:
I Picked up Gun X Sword thinpack boxset (above) at the last expo, despite the obvious "fanservice qualities" of the characters on the cover, its not really like that. Okay in fairness the one in the background is called carmen 99 (99 in reference to the size of her boobs according to the shows main character)
If you haven't seen it yet i'll try to sum it up, Its generally episodic with a main story trailing through it, every episode includes a good storyline for its 30odd minutes, giving small parts of character history, motivation and leads to further adventure/search for a main "thing/someone" by the end i believe its meant to tie up the story and it turns more serious. In fairness i'd compare aspects of it to the following shows: Bakuretsu tenshi (Burst angel) for the sudden mecha fights that appear out of the blue, the remainder of the episode doesn't usually have mecha appearing 3-4 times. its usually the main characters doing things. Cowboy bebop - okay, now its not based in space and they aren't bounty hunters, but the main character (Ray?) reminds me of spike. similar looking and similar body. even wears a "tuxedo" 99% of the time..... Spike wears a suit 99% of the time. Worth giving a watch i'd say.
