Designed as a 1/1 scale plastic model, the Megami Device B1R-L Chassis Kit Skin Color E blends bishoujo aesthetics with rugged armor and weapon systems. This kit offers two color configurations—concept color and full-body skin color E—allowing modelers to tailor the look and even reuse parts across other characters. The large-size machineca is equipped with printed movable eyes on the included face parts, plus an unpainted face with blank movable eyes compatible with decals. The helmet's expression can be shown or concealed, and the articulated fins enable a variety of poses. Shoulder blades are included for broader compatibility, and the chest, abdomen, and torso parts can be swapped to adjust detail levels. A back armament hanger with a 3mm connector, a small eye-adjustment tool, and a stand for one-legged poses complete the kit.

Megami Device models exist at the intersection of stylized character design and mechanical combat. The B1R-L Chassis Kit Skin Color E is a reimagining of the Block1 large-sized body, reborn as a versatile chassis kit with improved mobility and easier assembly while maintaining compatibility with past kits. It introduces two main configurations—concept color and full-body skin color E—to give builders broad color options and to facilitate use of parts in other projects. Sculpted by Masaki Apsy and developed with the collaboration of guest illustrators, the kit emphasizes modularity, printed detail, and 3mm joint compatibility for robot battles. It invites hobbyists to mix and match faces, armor, and accessories across the Megami Device lineup, creating unique characters and dynamic scenes.
