Anyway I'll try to keep this short because you should already know exactly what to expect from this if you've seen the first season (which you should have if you're reading this). Although it's naturally very similar, I personally think this season is slightly better than the first one, because it has a bit more focus on the show's main strength, in other words moe. I don't think there's ever been an anime which makes me rape the screenshot button as often as this one does, and there's a good reason for that. Especially Chino has an abundance of unbelievably cute scenes this season, which is surely intentional given that she's the series' main poster girl as far as pure moe goes.
The character cast is overall the same as always, with the one exception of Kokoa's older sister Moka who is introduced for the first time this season. In a nutshell, everything that Kokoa wants to be good at but isn't, Moka is. In other words, she's basically a "better" version of Kokoa, much to the dismay and jealousy of her younger sister.
The art style is about as cutesy as it can possibly get, even more so than I recall it being in the first season, which in this case can only be considered a good thing. The more the merrier, right? As far as the new theme songs go... okay I'll just say this: the OP is similar to the one of the first season and certainly isn't bad, but nothing special. The ED however... oh my god. I'm sincerely at a loss for words. It is my personal pick for best ED of 2015, and the reason is simply that it contains the most outstanding 90 seconds in the history of moe. It is seriously the most nosebleed-inducing thing I've ever seen. Similarly it's also the first time I've ever seen an anime's first episode discussion thread being filled with more comments about the godlike ED than the episode itself, just to put it in perspective. I seriously can't praise it enough.
In any case, if you watched and enjoyed the first season of Gochuumon wa Usagi Desu ka, then there's no reason you shouldn't watch the second one as well. It does everything the first one did, except it does it better. If there's any anime which can truly showcase what the very epitome of moe looks like, it's probably this one.
