This is an unexpected good find on my part. I honestly wasn't looking for much when I started reading this manga, but when I got far enough into the story (I think the second major story arc?) the story started to pick up and the characters became fuller. And the art is just plain outstanding. The action scenes are very beautifully drawn, I personally got a great sense of the movement during the fight scenes.
Also, I have to admit, the ecchi is great.
Overall, I am thoroughly enjoying this series. It has a lot to offer and brings out more and more story and plot elements as new characters are introduced. I highly recommend this to anyone who wants a good fighting manga that has plenty of action and ecchi spread throughout, and wants a good, interesting plot to go with it.
