Rio Tsukatsuki.
Rio is the definition of "calculated." As the President of Seminar, she oversees the entire school's finances and operations with a gaze so sharp it could cut glass. She’s often called "Big Sister" by the other students, though it’s a title she carries with more stoic authority than warmth. Personality: She is a perfectionist who believes that everything—emotions included—can be boiled down to a mathematical equation. She’s cold, efficient, and rarely shows vulnerability. The Secret: Underneath that robotic exterior, she actually cares deeply about Millennium’s safety, often taking on massive burdens alone because she doesn't think anyone else can handle the "logic" of the situation. The Flaw: Her biggest weakness? She over-calculates. She thinks she can push her mind and body to 100% efficiency 24/7, which is exactly how she ends up collapsed on a gym mat when her "data" ignores her physical heart rate.
