The 7th HG kit from "Mobile Suit Gundam GQuuuuuuX" has arrived — it's Xavier's Gyan (Hakuji-Packs). It's a redesign of the classic Gyan done up in GQuuuuuuX style, and compared to some of the other units that went through more radical changes, this one feels relatively close to the original.

First off, thanks to the color separation and gold foil seals, it already looks great as a straight build. That said, the color scheme isn't particularly flashy by design — it's pretty much a monochrome combination overall, which makes it feel a little plain. The gold seals do help add some accent, and they're easier to apply compared to the GQuuuuuuX kit, which is a nice touch. The overall build process feels like a standard polycap-less HG kit — nothing too tricky.

For weapons, you get the Gyan's signature large round Gyan Shield, a lancer called the Hakuji equipment, and a beam saber. Both the 21cm Hakuji equipment and the large Gyan Shield lock onto the hand/forearm very securely. On top of that, the articulation is solid and the joint strength is excellent, so it can hold those big weapons and maintain stable poses. The instructions suggest using the support stand to prop up the Hakuji equipment, but if you balance the center of gravity properly, it can hold up just fine without it.

That said, if you're going for poses where the weight is heavily shifted, or if you're displaying it on an action base in the air, you'll probably want the support stand. The issue is that the stand needs to attach near the handle of the Hakuji equipment, which isn't really the most effective spot given where the center of gravity sits. It's better than nothing, but the help it provides is pretty limited. On the other hand, the Gyan Shield locks on extremely securely with its double-mount system, and it also has the 6-mine opening gimmick built in.

The beam sabers are stored on the sides of both thighs. It's a bit of a hassle since you have to remove them from the thighs and swap the handle out for the larger one before you can hold them. That said, the wrist does have a joint that rotates widely up and down specifically for the beam saber, so you can angle it like you're holding a lance or fencing sword, which works out nicely.

Overall, the solid styling combined with sturdy joints and secure weapon mounts means you can confidently strike poses with those big weapons — that's definitely worth praising. On the flip side, the polycap-less joints are very stiff, which makes posing feel a bit uncomfortable and even raises some concern about potential breakage. Given the large weapons involved, it seems like the joints were intentionally made tighter, so it's a bit of a trade-off. Either way, as a GQuuuuuuX-style new take on the Gyan, at least you don't need to worry about things falling apart — so keep that in mind and go for it if you're interested! :-)
