This one was just a random project I thought of. One of the things that is interesting about this series is all the monster girls that call it home. It would then be interesting if the author created a Monster Girl Encyclopedia will information about the monsters that call Eden home. This way the audience can get information about the ones we know about but also learn about monster races we haven't meet yet. The book can even have picture to give people an idea of what they look like along with the images of characters that fits into each receptive race that we have already been introduced to. I know such a thing would not be likely since it would take a lot of work to put it together, but it sound like a fun little side thing to have to help expand the world a bit.
