Let's consult my notes for a brief recap:
Shrine Mother Komari Kurokawa (黒川 小毬)
An older nine-tailed floof, physically perhaps in her mid-fifties by human standards. Somewhere a little more than two hundred and fifty hundred years old at this point, having had her life extended by Keros because she's too useful to let die. She's past her childbearing years, but there are those who age gracefully, and Komari's one of them. Takes care of the shrine to Keros in the heart of floof haus and the attendant torii gate, and one way or the other, Kinu's future great-great-grandmother in-law.
Great-great-grandmother of Hitoshi, Nakano, Miko and Mai.
The amulet of transference/union and the hoshi no tama set into it are originally hers.
Serves as the final boss of fluff haus.
Skilled at kitsunetsuki, doesn't need a fox jewel to use it.
