Anime is great until the final episode
Up until the last episode, this series faithfully follows the manga. It's great seeing the characters animated in all their glory, but I'm saddened that the series ended so suddenly with the last episode, which wasn't at all how it went in the manga. Fans of this anime, don't worry - it's continued in the manga, which is up to around volume 50 by now. =)
Even though the ending was worthless, I hope the series is picked up for another 11 episodes anyway. :D
