Maidroid Rosalie presents a striking fusion of elegant maid aesthetics and battle-ready mecha design. The kit showcases a poised humanoid form with intricate panel lines and a pristine, high-contrast color scheme suggested by its official sculpt. The hands are made from flexible PVC to support natural posing, and the set includes smiling, half-closed eyes and other face parts for customizable expression, along with blank faces and eye decals. Optional components include a broomstick, dustpan, and a variety of attachment parts. Decorative water-slide decals and an articulated stand enable dynamic, display-ready poses, while snap-fit connections allow straightforward assembly.

Rosalie is a product of Tony's design lineage and Max Factory's engineering, created to protect a quiet realm where duty and loyalty are prized. In tales across the Guilty Princess series, she serves as a devoted maidroid companion whose primary mission is to shield her charges while maintaining impeccable service. Her cooperation with Sentinel shapes her role as a frontline guardian, wielding a suite of optional weapons that can be assembled with the Extermination Grenade Cannon Panzergeist or Portable Annihilation Vacuum Geo Destroyer. Though her persona is calm and courteous, Rosalie's spark of resolve ignites when danger arises, turning her graceful silhouette into a formidable defense.
