ok, I was right u have to follow the quest in that small fishing little to get the Kitsune in build .400 after you have done she will appear in one of the rooms upstairs. Unfortunately she seems to be in development.  I include a video of the quest in a bit 

Walk through 

The "spirit guardian" character is a kitsune, but appears to be an entirely different character than Hiyokuna, the blonde fox-girl in previous builds, with different character art.  The only similarity I've found is that they both occupy the same mansion bedroom (second from the bottom-left) once recruited.   She might be intended as a replacement, but with the fortune-teller still pointly towards Hiyokuna's dummied-out location, it's hard to tell.
