So the ending pretty much ended generically... But it was funny at the same time. Besides that, the action was decent and the characters acted the same as usual. As for the plot, it was caused by another lame reason why the villain caused the problem. It was just strangely funny.
Though the weirdest thing is what happened to this "brother" of Nyaruko that made an appearance in the earlier episodes? I find that quite strange that the creators did not do anything with him or at least put him together with the minor characters. Also, there's no other details about him. Is he just some kind of ghost? Anyway, the series overall was not that cheesy and it didn't really end up as other echii genre anime which is also another surprising thing. In conclusion, I don't have much thoughts but I think it would be kinda nice to have another season of this anime.
Conclusion: Would be nice to have another season...
Personal Note: Thanks to a friend that informed me, the anime title for most of my entries are wrong. I'll get them fixed soon.
