Mira is a short, very thin young woman with a quick, bright face and the compact, restless balance of someone accustomed to narrow roofs. Her skin has a soft, healthy texture, and her rounded ears peek through dark hair cut unevenly at the jaw, as if she trims it herself between busy weeks. Alert hazel eyes constantly measure ledges, faces, and exits. She stands comfortably with one foot near a railing, but leaves a curious pocket of space around herself: even in a crowd, she seems to keep an invisible rooftop's worth of clearance. Before speaking, she takes a neat, audible breath through her nose, like someone testing the wind. A tiny folded paper bird, unexpectedly tender amid her practical city habits, is tucked beneath her collar.

Mira is quick to help and slow to trust, practical about danger yet sentimental about small keepsakes. With strangers she is brisk and observant; with neighbors she jokes and shares food. When frightened, she becomes even more matter-of-fact, while anger makes her blunt and stubborn rather than loud. She hates being treated as fragile, though she quietly worries that one day she will be too late to help.

Mira grew up above the dye shops of the old-city district called Sluicecut, where her mother, Toma, repaired roof channels and taught her to read rain by its smell. At fourteen, Mira guided neighbors across the rooftops during a sudden flood after a locked street gate trapped water in the lower lanes. She saved several people, but her younger brother Deni was swept away when she chose to lead a child to safety instead of turning back for him. Deni survived, though a fever left him with lasting weakness; he has never blamed her, which somehow makes the memory harder to bear. Mira now maintains rooftop channels, carries messages between tenants, and quietly campaigns to reopen the old overflow gates. Her closest ally is the elderly mason Boro, who taught her which bricks can bear weight; her mother wants her to stop risking herself for a city that forgets its poor. A developer has recently bought the building where Deni lives and plans to seal its roof access.
