Nanbaka is, for me, a very easy-to-watch anime!
I haven't reviewed the first season, but I'll leave a small comment in the second one.
I rated the story 8. I find Juugo's story interesting, but as we're still in the dark about some stuff, I won't rate it higher. At least not until I get to know what it's all about! Still, Nanbaka's a funny and interesting series and this season is just as exciting as the first one.
Overall, I'll give it a nine. It isn't one of the best animes I've ever seen, but as I'm laying back after college, munching on a cookie and trying to forget about how much Latin's class kicks the life out of me, Nanbaka's a very chill series to watch. I get a good laugh at some scenes, the plot is interesting enough and the characters are just amazing. There's a variety of them and it's difficult not to like most of them, to be honest. They're the best part for me!
A must watch, if I do say so myself.
