If I recall correctly, everything after episode 14 is dirty rotten filler. Though based on how the manga is going now, I think Katou-sensei gave them some notes, or maybe she was inspired by some of the filler, I don't know.
...read the manga, because the most popular complaint about the anime, besides being dirty rotten filler, is the characterization derailments and the sheer underwhelming-ness of the series' supposed most powerful beings.

I recently finished reading the latest chapter of the manga, and I have to say I enjoyed the manga more than the anime. I liked the first half of the anime, but like shukketsumaru said, the later half of the anime was getting rather weird. It didn't follow the manga. I also think the manga is more powerful in delivering the characters, both good and bad, that it's more enjoyable than the anime.
