Air Gear is both an anime and manga. It's in the sports genre mostly, but the sport, air trek, involves a ton of combat. Air trek (A.T.) is like inline skating, but the skates have tiny motors in them. They're really strong motors that are even able to keep with a car. Air Gear's plot largely revolves around competition between storm rider teams (storm riders are the people who participate in A.T.), and Ikki, the main character, becoming "Sky King."The manga version is much longer than the anime, and is still ongoing. The anime's original run ended in September of 2006. I don't care too much for how the anime ended, I felt it left too much unanswered, but you can pick up where it ends in the manga, no biggie. Air Gear features a bit of a symbolic theme. But it's not one of those complex symbolic themes that requires close attention to catch, and you probably won't have to look it up on Wikipedia later. It's usually just an animal metaphor used to describe a particular person. Also worth noting is that the manga version contains some mild to comfortably spicy ecchi scenes, so you might want to be careful when you read it, but more often that not you'll be completely or mostly desensitized to it.
The artwork in the manga often gives characters really exagerated comical expressions like many other mangas do, but these are heavily exaggerated comical expressions: sometimes looking as if they were drawn in three seconds (undoubtedly intentional though).
Overall, I give it a perfect score.
