If anyone's interested, the Killing Stone is not only the actual real location, but also according to the Japanese legend, a kitsune named Tamamo-no-Mae was buried under it (or the stone was her remnants).
Since the newbies seem to have a connection (?) to Osaka, I wonder if we'll get a Kuzunoha reference.
I wonder if Nobimaru and Kon are related. Seems like they aren't from the same Ishimori clan, but they could live in the same place.
Also, both Inari's and Nobi's fur is dark-colored. I wonder if they are related?
