Story:
Very good and substantial. Only little deviations were made, making it more closely paced with the original work. Bridging the last season and this season is very well done (considering the small deviation in the first season's ending). I honestly like this one more than the manga (in terms of portrayal) since it was more appreciable (to me anyway). Bishamonten and Ebisu's arcs are not my fave in the manga, but after watching this it changed my mind. Truly awesome.
Art:
Soft textured drawings. Similar to the manga. Good animation (esp the fighting scenes, oh I so love them). I'm the type who watches anime regardless of the art, so I can't say a lot of things about this but I can assure you one thing: it's not sloppily made. I actually liked how it was drawn since it give off this sense of familiarity.
Sound:
Awesome opening and closing themes. "Hey kids!" give off that action-packed anime feels plus it has that catchy beat that I can't help but love. "Nirvana" has the same feels with "Heart Realize" (last season's closing theme). Sweet, cute, cuddly, and adorable.
Characters:
Strong female lead (Hiyori), hilarious and incredible male lead (Yato), and adorable second male lead (Yukine). If you love them last season, then you will still love them this season hehe. I have a pick of my new fave character as well (since they truly are amazing in this season) like Kazuma, Kofuku, and Ebisu. Oh my, young Ebisu is so cute I could die. Bishamonten is pretty awesome here too.
Enjoyment:
Absolutely enjoyed this show. Even enjoyed this more than the manga (pertaining to the respective arcs but the manga overall is still awesome hehe). This is my best pick last season.
Rated this 10/10 in MAL (personal taste hehe) but for now I'll go with 9/10. If you're looking for an action-packed anime with a lot of hilarious scenes that will make your heart flutter (sadly, the romance element wasn't emphasized but nevertheless it's still awesome), has a share of gore and blood (just a little bit), and drama I guess (well a small share too), then you definitely have to watch this. Time wasted while watching this is not even considered wasted time at all. Highly recommended. You didn't even need to read the manga for you to get a grip of things. But make sure you watch the first season (if you still haven't) to avoid unnecessary confusion.
Well, that's it. Ciao.
