Miru Sanzein, or "Rie" as she's known on stage, is a new Freak-Quency player who joined the tournament at the same time as Sonnya. She starts out fairly cold, but quickly grows to be one of Sonnya's closest friends as the story progresses. She has a very deep attachment to her voice, hence why she hates having her freak so much, and works so hard.

I imagine Miru with a very stereotypical teenage girl voice, at a fairly high pitch. She is very passionate and hard-working, which should be conveyed in her lines.
