There's a patch, probably created by a fan, that translates a small portion of the game into English. It doesn't translate any storyline bits, mostly just gameplay so you can tell what it is that you're doing. I'd provide a link to that but I don't remember where I got the patch and I don't know how to upload files of my own.
Ah, that's a shame. Well, one can only hope that in the near future, someone will translate the whole game, like how they did Monster Girl Quest. At least I think they translated it entirely for that game.
