Or The Fox God, Keros plays some scheme as always.
See s/he and Kiyoko needs more assistance in household and a proper lead Chamberlin for Kiyoko descendants.
Either Miko or Mai will become Den matron and Komori secretly disappear from public while the Otomo residence has a new Grand Chamberlin from Kurokawa main clan. :3
No one suspect a thing because they saw new Chamberlin who wears think veil has the same body portion as Komari.
In reality, the new Kitsune Chamberlin either a fake out create by Keros or joining the PC party (or simply station somewhere or kill-off by the time).
Komari was forced by Keros to take the Chamberlin place and gets some change in appearance likes to remove glowing-eyes or change the glowing color, but most other things as remain the same. This make the other Kitsunes feel difference aura and through she is difference person who has identical thick body, and the Previous Matron has pass away after Keros removes the curse.
....
If Mai or Miko become Den Matron...
As either one needs an heir.
We may officially impregnate another one will out do something to the game code. (Give difference dialog)
