The crawling chaos Nyaruko is coming back.
The incredibly vibrant gang of aliens will be coming back to harass Mahiru yet again in an all new, second season. This was greenlit recently, although I can't say that this was unexpected.
Honestly, I'm more psyched for Haganai's second season in January lol, not to mention this amazing fall lineup coming to us in about a week. But I always like to see stories continued.
