Hide Osako

When Hide made her appearance at the Bitokukawa Administrative Office a few months prior, few expected that she would leave the building, not as a normal student, but as a rising Ultimate. But within the pages of the book she carried lay a thesis on medicine - a work dominant in its intellect yet remarkable in its accessibility. Even the headmaster, lacking any healthcare background, found himself enthralled by Hide's exemplary brilliance. It came as a surprise to learn that, at the time of writing the paper, Hide was merely a junior nursing student. Bitokukawa had once again demonstrated its prowess in identifying society's modern geniuses whom conventional education might have overlooked. Her treatise was entrusted to the Academy for thorough and discreet examination in service of societal advancement.

Hide's title of "Ultimate Theorist" underscores the breadth of her expertise, which extends far beyond the confines of medicine and into the realm of philosophy and truth itself. Affectionately nicknamed "Girl A" by her peers, she is sure to maintain the same precise theories and confident demeanor that she exhibited during her pivotal encounter with the headmaster.
