extremely important to point out that her villainous scheme is to make her world such an unimaginably excellent place for everyone to live in that it fundamentally upends the existing power structure and essentially only punishes the small handful of privileged shitheads who were mean to her headmate girlwife
Y'know, people (me) can say shit like "there's too many isekai" or "anime is too formulaic" but they are truly on levels of genre fuckery that we can only dream of.
It's actually really sweet when she says her dream is "Creating a world where someone (Emi) with a kind heart can live in peace." She is extremely committed to Emi over everything and everyone else.
I also want to mention another thing I love about the series, but... it might be a small spoiler, so I'll put it below a Read More.
I love that she is never found out. Everyone believes her act until the end. It's something I love about Fake Saint of the Year as well. No one discovers what they're like on the inside, because they're so committed to the act.
If anything seems a little strange, everyone is willing to disregard it because She's Such A Good Person.
