What Mira doesn't understand is that Ren doesn't like animals because they are cute... she likes them because they are inferior.
If she could put a collar on someone in public and go around with them she would as easily as she walks with her dogs.
Ren's mind is twisted, she received too much praise and too much power too early in her life.
Fubuki's answer kinda got me by surprise, she really wants to focus on unmaking the toxic atmosphere that her mother fostered in their family, and I respect that.
Yakumo's answer was something I kinda expected, she is a neutral party, I think she is pretty satisfied with her standing as long as things profit her she will keep her duties at a minimum and do her own thing, she is pragmatic in a self-centered way.
About Tobera's tenure as commander... as much as I think keeping the government at arm's length was a good thing... i doubt she did it for anything besides her own satisfaction, I wouldn't say she is a control freak like Ren, but she is just as much of an egomaniac, maybe more, as Ren does likes to use more sophisticated tactics.
And unfortunately... I doubt Mira has much practical chance of winning, Kyouka may be an idealist but she knows how to play politics, she would rein in the agency and the government but she would work with them, Mira is even better than Kyouka in the moral spectrum... but she TOO idealistic, she is giving too much chance and not keeping her wits sharp enough.
In any other situation, I would love for her to be the commander, but with an enemy of such a level, someone who can be more pragmatic is better.
