This kit is the HGUC Cruiser Mode Booster Expansion Set (Combat Deployment Color), released as a Club G (Premium Bandai) online exclusive. It's essentially a color variant companion kit to the simultaneously released white test color booster — only the molded color differs — and it's used to combine with the HGUC Hazel-Ra II and the Hazel-Ra Second Form. All structural features are identical to the test color booster.
When attaching it to the HGUC Hazel-Ra II, you'll need to swap out the drum frame on the back with the connecting drum frame included in this kit, and the fit is quite solid. It's still not the easiest thing to pose given how much is hanging off it, but even just standing there it has an incredibly imposing style and sheer volume to it.
Second, it can also connect to the HGUC Hazel-Ra Second Form using the dedicated joint parts, and with the massive long blade rifle thrown in, the whole thing comes together as a slim yet elongated form stretching all the way to 60cm. It looks great, but it's a bit of a handful to actually handle — that said, just like the other configuration, it has a presence that absolutely commands attention even when standing still.
Either way, posing things with the booster attached isn't exactly easy, but as something that maximizes sheer volume even in a static display, it feels like a great fit for the AOZ concept. If it's your kind of thing, it seems like a pretty easy buy. :-)
