I really liked this anime because it was very uplifting and very motivating. The energy and honesty you'd see in Yajirou was really bad ass -- I even dressed up as him for anime north. Also, Rushuna was just a great person with whom to team up. She was a really nice person with a respectable stance on things. The whole story would focus on the benefits of positive actions and views of life -- peace vs war, happiness vs. sadness, optimism vs. pessimism. That being said, the plot could have gone a bit more in depth with these themes. On the upside, the characters were likeable and the animation and sound were both great.
If you're here to see ecchi, then yes, this show is awesome for that too :)
