Jun 25, 2025
The Megami Device B1R-M Chassis Figure Kit (Skin Color A and B) brings a fresh take on Kotobukiya’s beloved line of bishoujo-style mecha model kits. As a remake of the original Block1 standard body, this kit delivers improved mobility, better proportions, and easier assembly while maintaining compatibility with past Megami Device releases. Whether you're a longtime fan or new to the series, this kit offers unmatched customization potential—perfect for builders who love anime-inspired mecha girls.
Key Features of the Megami Device B1R-M Figure Chassis Kit
1. Redesigned for Better Articulation & Compatibility
The figure represents a significant upgrade to the original Block1 body, now optimized for smoother posing and easier assembly. What makes this kit truly special is its backward compatibility - it seamlessly works with older Megami Device kits, enabling creative hybrid builds. Modelers will appreciate the swappable chest pieces compatible with pre-Buster Doll models (shoulder blades included for easy installation). The thoughtful helmet design maintains visibility of facial expressions even when worn, while the included 3mm connector on the back armament hanger allows for attaching existing parts from your collection.

2. Two Body Types in One Kit
This versatile kit offers builders two complete aesthetic options: the standard concept color version and the full-body skin color (available in both A and B variations). Beyond just color choices, the kit provides unprecedented customization through interchangeable parts - including both high-detail and simplified components for the chest, waist, and feet.

5. No Paint Required (But Customization Encouraged!)

The color-separated design means no painting is mandatory, but the compatibility with Megami Device and Frame Arms Girl weapon systems invites experienced builders to create expanded loadouts and personalized configurations. Whether you prefer a quick build or an extensive customization project, this kit accommodates all skill levels.
