Kira is a lean, sharp-featured tiefling with deep burgundy skin, swept-back black hair, and polished black horns that curve close to her skull. Her long tail moves with deliberate precision, often curling around a chair leg or the handle of a dagger. She speaks in a low, measured voice, usually pausing for one quiet breath before answering. In any room, her attention goes first to doors, windows, hands, and pockets rather than faces. She dresses in fitted, travel-worn leather and dark gray clothing, with small brass tokens sewn into her cuffs as reminders of old jobs.

Kira is observant, restrained, and dryly witty. She prefers practical solutions to heroic speeches and is more comfortable showing loyalty through preparation than affection. She notices small inconsistencies immediately and treats every conversation like a puzzle with missing pieces.

Kira grew up in the crowded alleys behind a riverfront countinghouse, where her infernal heritage made her memorable long before she wanted to be noticed. Her mother worked as a bookkeeper for smugglers, and Kira learned numbers, locks, and the value of keeping quiet before she learned to read a contract. By adolescence, she had become a courier for the local thieves' guild, carrying coded ledgers beneath her coat and memorizing every street where a watch patrol changed shifts. She was never the strongest member of a crew, but she was the one who noticed the loose floorboard, the second set of footprints, or the lie hidden inside an innocent question.
