Mura-no-mitama-no-ōkami's Links
Gifted the fox at a young age already with his power and drafting him before anything seemed to have been wrong back then. Izanagi is most likely the closest a person has gotten towards Murakami since his fallout with his sister.
Adores him, loves him, follows him everywhere blindly.
Shows not much about how he actually feels about Sadao. At first didn't even seem to know about his existence but later on in the story it comes out that the man of the couple who found the boy and took care of him until the war broke loose(and Sadao getting kidnapped) was actually Murakami in disguise.
Isn't sure how to feel about him. There's something that makes Sadao feel like he should stick to him, especially once Murakamis mental state deteriorates.
It's currently unclear how exactly they know each other especially considering that Miyuki and her clan fought on Shimire's side during the war.
