There isn't much of a story at the moment - the Gijinka are almost like Pokemorphs, as in part human part pokemon. Gijinka are generally spurned and looked down on by society, but there is an Academy on a secluded part of Unova where the Gijinka can go to learn and just be out in the open without fear. That's generally it, but the best way for you to get the story would be to read a few posts - I find the very beginning is a very good place to start :) haha
