I am one of bureaucrats of this wiki. Natsume's Book of Friends is always one of my favorite anime/manga. I start watching this anime, reading chapters when I was high school student around 10 or 11 grade because I need to find spirit/youkai anime/manga and then this anime/manga is very emotion, heartwarming and best anime/manga I ever seen.
I owns Volumes 1-23 in English Version.
