What does your character think about the event aftermath?
While you couldn't tell just by looking at her, Mitama is both saddened and frustrated by the event, and most of all, by her own helplessness and inability to contribute more to the fight. She might hold a grudge towards the Rumpiturians, which, ironically, is a sign that she is siding with the Chosen, but she'll ignore it for now and focus on pretending Everything Is Fine. Also, she does keep in mind that the monster hasn't been defeated, so she will begin gathering and storing whatever supplies she can in her shop just in case.

How should The Chosen deal with Rumpiturians?
Despite her personal feelings on their actions, Mitama will choose to remain neutral and abstain from voting either way. you're not fooling anyone, girl
