I honestly didn't expect I'd enjoy this as much as I did. I was only going to watch six episodes, but I ended up finishing it in one sitting. I came here for the handsome fox spirit, but I stayed for the bond. Don't expect much story from this. The only focus of the anime was the random shenanigans that happened in the life of Kokkuri and Kohina. The familial bond developed between the characters were so sweet and funny to watch. I like the type of humor used and the savage dialogues. It was just a light watch. I'll try reading the manga in the future since it's complete because I want to see more of Kokkuri and Kohina.
In terms of art, I found it adorable. Kohina is usually in doll mode, and the others typically switch between their human-form and animal form. The human-forms are good-looking, while the animal-forms are so cute. I usually have a crush on fox-spirit characters, so that's a bonus.
In terms of the characters, I liked Kohina and Kokkuri. Kohina is such a mood in her coping mechanism. You can see how much she doesn't want to acknowledge her feelings because she's scared to explore new territories. On the other hand, Kokkuri is such a wonderful fox spirit. There were times where he was a bit weird, but you can feel how much he cares for Kohina. I love their bond. Inugami was a bit too weird, but there were rare times where I liked him. Shiragaki is hiding his personality - he is adorable. The other characters weren't that necessary, and they don't contribute much to the plot except for comic reliefs. There isn't much progress to the development of the characters, but I guess you can't expect much from a twelve-episode anime.
NOTE: If you don't want to stick for the whole twelve episodes, only watch the first and last ones. They were the best, and I enjoyed watching it a lot.
If you want something light, heartwarming, and your type of humor involves savage dialogues, stupid interactions, green jokes, then you should watch it.
Would I watch again: I probably might, but I would skip some episodes.
