Thanks, I'm very much a big fan of the games, along with this was how I got into the fandom.
I got the dojin though Amazon Japan, as CyberConnect 2 was selling both of them to fans who couldn't make it Comiket. Fanbooks I got through another person on GAF who lives in Japan and was going to Tokyo for the weekend. Asked him if he could get these for me while they were in Akihabara during the trip. CyberConnect2 does sell their merch not only through their own online store and Amazon Japan, but they do sell in a few Japanese stores like Akihabara's Kotobukiya.
The rest of collection along with a set of two wall scrolls of the characters from the game all came from amazon japan. Like I said before, they sell all their merch on there, though I did have to use a forwarding service just to get most of it here. Because they only ship CDs, books, DVDs, and Blu-Rays outside Japan. Pain in the butt, but was worth in the end.
I would recommend that you check out their
Kemono Fanpage on Facebook, along with their English CyberConnect2 Facebook as well, as they're very much kemono fans who have a love for it as well, and will talk about upcoming releases of either their Kemono or Solatorobo/Little Tail Bronx related merch from time to time.
