Youmu's always been this guy's favorite, so it was inevitable she got a book just for her. I'm sure she's thrilled. http://www.melonbooks.com/index.php?main_page=product_info&products_id=IT0000191058
I've just been waiting for the MC game which is made by this guy and Nyuu...but all they have released is a demo. Also some of the MC works don't have a DL version available... Great work! Thanks for uploading.
