Rei Sunada, the Ultimate Ballroom Dancer, embodies elegance and poise in every aspect of her life. Classy and meticulously put together, she approaches both dance and daily interactions with a serious demeanor. Rei values discipline and precision, which extends to her interactions with others; she tends to treat everything as a serious matter, often lacking a sense of humor. Jokes and playful banter are not her forte, as she prefers to maintain an air of sophistication. While her intensity might come across as stern, it stems from her deep passion for her art and a desire for excellence, making her a formidable presence on and off the dance floor.

For Rei's voice, we are looking for a low-spoken, authority figure-type voice. Rei should sound forceful, as if she controls everyone else in the cast.
