"I am not speaking of likes or dislikes... only facts."

Tsukatsuki Rio, former president of Seminar and student council president at Millennium Science School, is characterized by a cold, calculating demeanor. Her leadership style is largely influenced by her focus on objective facts, often sidelining emotions. Despite her high-ranking position, her approach to problem-solving is often reckless and deemed irresponsible, leading to criticism. However, her caring nature emerges in her interactions with certain people, demonstrating her readiness to lend a hand when necessary.
