How is it better? First of all is the story. Things got more explained here. Another thing is that the animation is improved, as a proof, if you watched the first season, you can notice a big difference with Chihiro's appearance. Yes, the humor and the cuteness is still there. Plus, the harem is a bit better than the previous season part which is another demon like Elci.
So in conclusion, if you are into the romantic comedy plus harem type then you would definitely like this anime. It is definitely a must watch.
P.S. Season 3 is already green lit so better hurry so you wouldn't miss out the fun.
