The daughter of Emperor Molto Sol Augustus, she's basically Japan's lifeline to the empire—the person holding everything together between two very different powers. She figured out pretty quickly that there's a massive strength gap between the empire and Japan, so she's been working constantly to keep her country safe and relevant.
Her whole perspective shifted after meeting Itami. She got pulled into otaku culture through him and it actually stuck with her in a big way—fans often note how her interests changed pretty dramatically after that. She's also the founder and leader of the Rose Order of Knights, which has become a significant part of her role in bridging the two nations.
