The visual difference with and without seals is huge.

Due to the center of gravity, when placing it on a flat surface you have no choice but to lean it forward like this.

Put it on a stand and you can display it horizontally.

Underside view

Like recent SD kits, you can rotate the eyes to switch to a pupil-less eye look.

Bring the head antenna together to the center, lower the mask, then flip the ankle armor 180 degrees..

...and you can get it into Kakure form like this.

Generous weapon loadout

Weapons can also be stored on the forearms and backpack.

Two hand parts are included, but you can see some sink marks on them.

Only one official leftover part.

Thanks to the Cross Silhouette frame, the elbows and knees can bend too.

Transformation

To transform into Nintodo form, you first need to disassemble the parts.

Disassemble the SD head and combine various parts to build the upper body.

Transform the SD head into Kakure form, attach a joint part, and fix it to the backpack.

Reassemble the arms and legs to extend their length, then attach them to the body.

Completed Nintodo form

You can combine various parts onto Hattori's body to create a large weapon configuration.

Articulation in Nintodo form.
Articulation isn't great, but the parts fit together nicely.

The SD RX-Zeromaru has been released as part of the Build Divers lineup. It follows a similar format to the Build Fighters HG Star Winning Gundam — a kit that can transform between SD form and a standard HG-style form.

First off, the base frame uses the SD Cross Silhouette frame, giving it those sleek SD proportions. Thanks to the CS frame, the elbows and knees can actually move, making this a pretty dynamic SD kit. As you'd expect from the latest frame, joint strength is solid and everything holds together well. On top of that, a good number of weapons are included, so you've got plenty of options for different poses.

As the name RX-Zeromaru suggests, it's based on the Unicorn Gundam concept — and just like the original Unicorn, you can bring the head antenna together and lower the mask to switch from Shinobi form to Kakure form. There's also a bird-type unit called Armed Armor Hattori included, and by disassembling and reassembling both together, you can transform it into a standard HG-style unit called Nintodo form. In Nintodo form, the fit is more secure than the real form of the HG Star Winning Gundam, giving it a pretty solid look, and paired with the large weapons you can pull off some seriously imposing poses.

So as a Musha Gundam-style take on the Unicorn Gundam, this kit has great proportions and dynamism thanks to the CS frame, plus a fairly solid transformation into real form — all of which makes it a really fun kit to play around with. Sure, there's quite a bit of seal work involved, but that also means the straight build looks decent enough on its own. Anyway, if the style is your thing, this is a fun kit I'd highly recommend. :-)
