It's kind of heartbreaking for Yuu to put on a strong face for the sake of politics even after she has made clear her wish to live in her natural body, as a girl. I expect Queen Riche to be the biggest antagonist in this arc considering (IIRC) it was her idea to get her daughter cursed in the first place to further her political ambitions.
Okay, that backstory with her backstabbing bullies on Earth had a darker end to it. Even though Misaki was suffering living as a girl, that was no excuse to be a despicable backstabbing bully.
I'm rooting for Rae and friends to succeed, I want to see Yuu restored to her natural body. Also I want to see Rod and Thane's reactions to learning they have a younger sister instead of a younger brother (assuming they don't already know).
