I want an action anime where the protagonist has a highly unconventional weapon choice. Basically a thing you'd never think could be used as a weapon, but they use it and it's awesome as fuck. The dumber (in a good way) and more abiding to "the rule of cool" it is, the better.

The absolute best example of what I'm looking was in the first episode of Ga-Rei: Zero, where there was this chick who used her motorcycle to fight - she did lots of tricks with it and used the wheels to tear the enemies apart. Video below:

I want something with that level of absurdity and awesomeness.

The plot should be something simple and easy to follow (I just want to turn my brain off and enjoy the action). Also, the more over the top violence there is, the better - it makes the action sequences all the more enjoyable for me.
What I don't want is fanservice and ecchi. I can't stand it, period. Some skimpier clothes are okay, as long as it's not a common occurence, but no unnecessary nudity, pantyshots or other shit like that.

I'd also like the show to be a complete, self-contained experience with a conclusive ending - no manga should be required to be read from me to get the full story.

Any suggestions? It can be something older or newer, I don't care, as long as it meets my criteria.
