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.
