#I'd like to thing that tengu scroll had some influence for the creation FS. At the very least it's namesake.

Rereading Forbidden Scrollery. On the very first chapter, we have an amazing image of Yukari. Writing prose or something

I also found this bit of info interesting.

Apparently around 1659 a tengu from a forest was harassing people on a beach in Ito. A priest went a recited a Buddhist sutra and then a scroll was delivered to the temple as way of apology from the tengu and is kept at that temple to this day. And like stated in FS, as the scroll is written by a youkai, it is indecipherable to humans.
