One of the better ways I've seen in a fictional sport done right. Has some shounen anime-like aspects but otherwise it generally has a good mix of the sports and stuff and romance.
All in the setting. I enjoy the concept of a sport where players fly around and try to score points. The romance is somewhat middle of the road, it isn't bad but it's not stellar either.
