Miyabi transferred to Starlight School as an exchange student from Himezakura Private Girls' Academy. She's the type who comes across as serious and composed—graceful, even elegant in how she carries herself. She's genuinely hardworking, which tracks with the whole exchange student thing; you don't get sent abroad unless you've got the discipline to back it up.
That said, she's got this funny habit of getting flustered pretty easily, especially if she catches herself doing something that doesn't fit her usual image or if someone (usually meaning fans know exactly who) calls her cute. It's one of those endearing contradictions where the composed exterior cracks just a little.
