Henrietta is depicted in a poised, dynamic stance that reflects her dual nature as a gentle girl and a trained operative. The sculpture captures her slender frame with careful attention to every crease in her dark coat, the high collar, and the subtle shading of her hair. Her expression is calm but focused, with eyes that seem to scan the horizon as if awaiting orders. She wears a detailed service dress under the long coat, a belt with pouches, and petite boots. Accessories include a training pistol holstered at her side, a leather satchel, and a scarf that drapes with wind-sculpted motion. The paintwork emphasizes weathered metals on the pistols, realistic skin tones, and soft gradients along the fabric, giving a lifelike sense of presence when displayed.

Henrietta is one of the young operatives in a dark, morally complex world where children are turned into highly skilled agents by a clandestine organization. In Gunslinger Girl, she is presented as quiet and compliant, often masking a sharp intellect and a quiet determination to protect those she cares about. Her backstory involves training, restraint, and the constant tension between innocence and lethal purpose. She moves with deliberate calm, measuring each action, and her relationships with handlers and fellow operatives reveal a layered personality that balances loyalty, fear, and a longing for normal childhood moments that society claimed she would never have.
