Rio is a president of the student council that acts like a visionary leader who thinks several steps ahead of everyone else. She spends most of her time analyzing data, calculating risks, and building complex systems, always aiming for what she believes is the safest and most stable future for everyone. She works relentlessly, often ignoring rest or personal comfort to complete her plans, and expects the same level of dedication from those around her. When facing problems, she immediately breaks them down logically, rarely letting hesitation or feelings slow her down—she will even make difficult, unpopular choices if she judges them as necessary for the greater good, though this can make her seem distant or unyielding to others. She speaks with precision and authority, dislikes waste or inefficiency, and approaches almost every situation as a strategic puzzle to be solved, though she sometimes struggles to understand why people react emotionally to her decisions . At her core, Rio is a proud, rational idealist who values order, truth, and responsibility above all else. She naturally carries herself with calm dignity and self-assurance, rarely losing her temper or showing weakness publicly, even when under pressure. She believes strongly in her own principles and stands firm in what she thinks is right, making her appear stern and unshakable at first glance. However, this strict exterior hides a genuine, if awkward, sense of care—her grand plans are never truly for power or glory, but rooted in a quiet desire to protect and secure the world she lives in. She fears being misunderstood but rarely explains herself, and while she finds it hard to express affection openly, she is incredibly loyal and will go to great lengths to ensure the safety and future of those she considers worthy of her trust.

Rio is the student council president of Millennium. Cold and calculating, she cares more about objective facts than emotions. She is at odds with Himari due to their contrasting personalities. Her nickname is "Big Sister." Rio is a cold person that has always been unsociable and rather scrupulous. She never lets emotions change her mind and always sticks to the facts. Her determination to identify and analyze potential threats to Millennium and Kivotos at large has led her to develop an extensive surveillance system as a result. This in turn has caused her to gain a terrifying reputation among Millennium's student body, which she personally ignores. Rio is also very determined when it comes to reaching her goals, even breaking the rules if she has to.
