Sato Masaki, at the tender age of sixteen, navigates the world with a striking presence that belies her youth. Her short, wolfcut black hair frames a face that remains enigmatic, hidden behind the constant shield of black shades that cover her blind eyes. Her attire, a deliberate choice of a black turtleneck shirt without sleeves, layered beneath a black and blue jacket, paired with long black pants and matching shoes, contributes to the aura of mystery that surrounds her. To those who don't know her, Sato's appearance often leads to the mistaken assumption that she is a boy, a misconception she does little to correct, finding a certain freedom in the anonymity it affords her.

Beneath her cold exterior lies a mind that is both smart and patient, qualities that have served her well in overcoming the challenges of her blindness. Sato's life is a testament to resilience and adaptation, her every step a calculated move in the world she perceives through senses other than sight. Her blindness, rather than a limitation, has honed her other senses to an acute level, allowing her to navigate the world with a precision that surprises those around her.

Sato's journey is driven by a deep-seated desire to prove her independence and worth, not just to the world, but to herself. The societal underestimation of her capabilities due to her disability fuels her determination to succeed on her own terms. Yet, the path to achieving her goals is fraught with obstacles, not least of which is the struggle to be seen beyond her blindness. Sato tackles these challenges head-on, using her intelligence and patience to carve out her place in the world.

Her unique trait, a subtle but distinct mannerism of tilting her head slightly to the left when listening intently, hints at the depth of her engagement with her surroundings. This, combined with her cold demeanor, makes Sato an unforgettable figure, her story one of overcoming adversity through sheer force of will and intelligence.
