Anime style watercolor illustration of three young female prison guards in blue uniforms. The central guard is holding up a large ring of keys with a triumphant expression, while a metal case overflowing with keys sits open in front of her. The other two guards are looking on with curious and surprised expressions. The background shows blurred prison bars and a sense of a dusty, possibly smoky, environment. The overall mood is dynamic and a bit mischievous, with a focus on their facial expressions and the abundance of keys.
