This kit is from a manga, based on the Build Divers show, but is used and made by a different protagonist.
The basic idea is that you have a small Gundam model compatible with the various Build Diver 'Planets system' kits, the Mercuone, Veetwo, Earthree, Marsfour, Jupitive, Saturnix and Uraven, and then of course its own parts which are the Anima Rize.
This kit is more involved than most of the other Planets Build Diver kits, as you get some nifty parts that also function as 'bits' (autonomous flying parts that fight by themselves, which are the arms and legs).
Each extended limb has a little animal foil sticker, giving it a nice effect behind the smokey black translucent plastic.
There is a large beam saber hilt with a straight beam and a "whip" beam effect.
There's also a detachable back skirt that functions like an equippable shield and the usual beam spray gun has a huge bone like extension that makes the gun into a bigger rifle.
You can kitbash the parts on these with any of the aforementioned planets kits. The "Marsfour" which features red armor parts is a good match for this and you can make a completely red core gundam.
Another interesting part is that you get almost an entire spare set of armor, this time translucent, which has a ton of kitbash and customization potential for this line of kits. There are some parts missing however, like ankle joints. You will need to get another kit to fully flesh this out.
