Haganai season 2 is over and it ended in the most unexpected way possible. I think the fans of the series will either love or hate the ending depending on which characters they like but all in all, the entire series is just very, VERY good. I'm not going to hunt for the manga, which has two volumes for sale already.
This is one of the best Anime comedies I've seen and now understand the popularity it has all over the internet. The characters are serously well-created, hilarious, strange and funny and the things they do and happen to them are excellent. Fortunately, it's just 25-episodes long so watching it should only take a few hours. I seriously recommend it.
