First, the story. Even if I love it, I must say it's a bit simple (excluding character's development), I mean, it's a series of fight, even if there are some events which come enrich the story. The humor, just like the fights, is pretty good.
Second, character's development. I rarely see a manga with such great and well-developed characters. Everyone is fascinating, even the useless ones. It make the story much better, because we know why all of them are fighting.
Finally, the art. Every panel is powerful enough to give you shivers. The fighting ones might be some of the best I have ever seen, and the funny ones are nice too. The cutting makes fights really energetic, we can feel every blows, and even the strength put in each one of them. There are some nice idea of drawing, it innovate every time and never let you getting bored.
To conclude, Kengan Ashura is one of the best manga I've ever read, it's an example for all fighting manga, you must absolutely read it !
