Rio has always been unsociable and rather scrupulous. She never lets emotions change her mind and always sticks to the facts. Because of this, a lot of students find Rio to be terrifying, but Rio doesn't let their opinions into her head. Rio is also very determined when it comes to reaching her goals, even breaking the rules if she has to. Physical attributes are that she's 6 foot 2 inches tall, weights around 64 kg. Although she is part of the Seminar, she is coincidentally very strong.
