I didn't think there was going to be a season three of GnS. I did enjoy it a lot, though. More than I expected to.
I'm not sure what anime you're referring to with the 'magic book of friends,' but I also enjoyed Barakamon. The ED is really nice.
I was on an anime drought for a while due to my previous job and school taking up my time, but I'm going to be watching quite a bit of stuff from the spring season coming up. I also intend to start Erased and I started Dagashi Kashi.
