GeGeGe no Kitarō
Toward the end of the Shōwa period, on the basis of Fujisawa's interpretation given by the caption, the thought that they "come into one's home" or that they are a "supreme commander of yōkai" took a life of its own after Mizuki Shigeru and Arifumi Satō spread them through their own illustrated yōkai reference books, and in the animated television series, the 3rd "GeGeGe no Kitarō" (starting in 1985), a nurarihyon was the antagonist and arch-enemy of the main character Kitarō, and was a self-proclaimed "supreme commander," which altogether can be seen as things that made their perception as being "supreme commanders" even more famous.
