When they put this Light Novel in the local bookstore's shelves, I know I had to buy it (and I am). Originally, I only interest with the art since it's drawn by Kantoku but the anime is quite decent. Since I can't read Japanese and the book IS in Japanese, I only able to skim-through the book and imagine based on the anime and picture in the become, but I indeed able to feel and enjoy. Surely I'll read the book once I able to read Japanese.
I'm sure that the Novel and the Anime don't have much different except some part is about when is
when and naturally the character design in the Light Novel is waaaay better than the anime.
One more thing that I found interesting in the novel is, occasionally you'll see character stat in the novel (and fan service) like when they play TRPG or How-To Ribbon Tutorial, and once again that you can say that the novel is somewhat a fan service in a form of book.
