I've wanted this doujinshi for a long time, it's from 2011, and it isn't really being sold anymore, so I'm going to make this my first public scan. I'm sorry for the quality in certain spots, if the demand is there I'll redo it (if you're a translator I will go extra hard for you). I have a few more books from this artist starring Felynes on the way, including another Nyanjiro book.
