From a Japanese Historian friend:

The interesting thing about TENGU story is, it all time involves smart teenage or boy kidnaped by TENGU. 

They bring them to the mountain and train them there. Never heard a story in which TENGU kidnaps a girl.

By the way, all TENGU"s are males. No female TENGU.
