音無き世界 : SHYノベルス
This is the cover of the Novel of Rio Sugihara which was illustrated by Takarai Rihito, published by Shy Novels in Japan. For those who are interested in buying this book, you can buy it via amazonjp.
I posted this just for people who are fans of Takarai Rihito and are wondering what the image(which can also be found in her blog) is about. So there you go! It’s a novel!
