UMS004 Super Action Female Body is a highly articulated 1/12 scale figure designed for dynamic display and photography. Standing approximately 158 millimeters tall, the figure is crafted from PVC, POM, PC and ABS to balance rigidity, poseability and durability. The torso and limbs feature multiple articulation points for natural posing, while the included set of interchangeable parts expands display options: an extended neck piece for dressing, seven alternative hand sets for gripping, weapon and item handling, and expressive gestures; additional shin, bare foot, sneakers and high heels provide varied stances. Detachable underwear parts, when worn, enhance realism. The finish emphasizes clean linework and subtle shading to highlight the sculpt and proportions. The product ships with a main figure and numerous accessories to support vivid scenes.

Within the Romankey universe, UMS004 is a versatile field operative known as Echo 04, a modular figure who can adapt to any mission by swapping components rather than changing bodies. Designed for collectability, the figure uses interchangeable limbs and gear to switch between stealth reconnaissance, close quarters combat or poised display. In the backstory, Echo 04 uncovers a conspiracy within a shadow organization that manipulates memories, guiding heroes and villains alike. Her missions demand precise timing, calm demeanor and resourceful improvisation, allowing fans to recreate scenes of intrigue, negotiation or action by selecting the appropriate pieces. Echo 04 embodies the fusion of technology and art, inviting collectors to craft personal adventures.
