Busou Shinki Oorbellen Lunaria MMS figure presents a compact, battle-ready silhouette crafted in glossy PVC with metallic accents. The armor plates are layered over a slender, articulated frame, creating a dynamic stance as if mid-stride. Lunaria's head features a molded helmet with a decorative crest and small sensors to mimic a living machine. Her long, lavender-tinged hair cascades down from beneath a stylized helm, while miniature rivets and panel lines along the armor emphasize the mecha-inspired design. The color palette combines deep midnight blues with pale silver highlights, and the figure includes interchangeable parts such as armor plates and posable joints. The surface finish is smooth with soft shading to enhance the sculpted curves and armor joints, and the overall look exudes a refined, collectible quality typical of the Busou Shinki line.

Within the Busou Shinki universe, Oorbellen Lunaria is a guardian android created by a private studio to protect her owner's data and possessions during patrols across a neon-lit city. She operates as a scout and frontline defender, using modular armor modules that can be swapped in the field to adapt to threats. Lunaria wears a set of ceremonial earrings that double as micro-drones, lending her a unique tactical edge. When danger arises, she moves with precise, graceful efficiency, channels power through her light-emitting weaponry, and maintains loyalty to her handler despite the challenges of shifting alliances in a world where technology and fate intertwine.
