This kit is the B1R-M Chasis Kit Skin color A released as part of Kotobukiya's Megami Device series. It's a set that comes with a new-format girl-pla body in two colors — a concept color version in gray and white, and a full-body skin color version, both included together.

Now, while it's billed as a new body, the overall layout is fairly similar to the existing Machineca block body. The joints have been improved with much greater forward-and-back movement in the waist and neck, and the limbs are made up of single-piece parts, giving the build a simpler, more streamlined feel. Being a new design, the joint strength is solid across the board, and the simplified parts count does make assembly easier — though outside of the waist, it doesn't really feel like the articulation has taken a dramatic leap forward.

That said, quite a variety of accessories are included. The head can be swapped between three faces including a tampo-printed one, plus a visor-style helmet that covers the eyes. The torso has swap parts for the upper body, waist, and panty sections respectively. There's also a toe-style foot, shoulder joints for compatibility with earlier Megami Device kits, and a head part for compatibility with Block 2. A weapon hanger for the back and an electric screwdriver are included as accessories too, and the screwdriver can even be used to adjust the direction of the tampo-printed eyes.

So as an improved new body, this kit comes with great quality and a solid range of accessories. You might wonder whether it was really necessary to pack in two copies of the body, but depending on your preferences, that could actually be a plus. Either way, if you're someone who likes body-type kits, this one should feel like pretty good value for money. :-)
