Shipping aside, I genuinely think Mutsumi should leave her toxic home as soon as possible.
It's just a fucking gigantic doll house that keeps its dolls inside quiet and docile.

Mutsumi needs to live "with" somebody, some actual humans in a place she can call it "home".
For instance, living with Sakiko and Hatsune would help fixing her DID and mental growth.
I think Hatsune's flat is too small for three girls so moving to a larger house and living together will be nice.
