To reiterate the relevant bits of my theory, the ooku (earth), has an overacting, or excessively destructive relationship to the karakasa (water) by damming it up and prevent it from flowing freely. Indeed, the waters within the ooku sit stagnant within bowls and the depths of a bottomless well.

One would think the name Utayama will be the very embodiment of that principle.

However!!! Consider this: her character bio states that despite her strict demeanor, she is deeply concerned for the women in her ooku. And many other characters within the cast seem to be plotting for her downfall.

I ask again: when would something as immovable as a mountain "sing"? During a mudslide or an avalanche - both of which can be caused by severe (water-based) weather conditions.
