The verdict

This is a kit for the AOZ faithful first and a general Gunpla release a distant second, and once you accept that framing it is a genuinely satisfying build.

The Owsla-style chest, the HRUDUDU II side units, and the brand new Psycho Blade mold give you a silhouette none of the earlier Hazel kits have. The catch is that it leans on the same runner system as the Advanced Hazel before it, so a chunk of what is in the box you may have already clipped off a different TR-1 kit.

Best for: AOZ completionists and Hazel-line kitbashers who want the Haze'n-thley-Rah II specific parts, not first-time buyers looking for a standalone showpiece

The full review

What it is

This is the Haze'n-thley-Rah II configuration of the Hazel family, built off the same core frame as the HGUC Advanced Hazel but dressed in Owsla-derived chest armor and carrying the HRUDUDU II side pack. What got me was how different it reads on the shelf from the plain Hazel despite sharing a skeleton, the side armor bulks the silhouette out and the new Psycho Blade gives it a weapon nothing else in the line has. Building it felt like assembling a variant kit in the best sense, familiar joints and cockpit block, but a genuinely new top layer of armor and gear on top.

The catch

The honest problem is the new joint connecting the HRUDUDU II unit to the side armor. The dowel is shallow and the fit is loose out of the box, mine popped free repeatedly during posing and reinforcing the peg with thicker plastic only bought partial improvement. This is also a Premium Bandai exclusive, which means secondary market pricing and no easy reshop if you want a replacement runner. And because so much of the frame is shared with the Advanced Hazel, if you already built that kit you are paying again for parts you have seen before, just to get the new armor and blade.

Who it's for

Buy this if you are already collecting the Advance of Zeta side story kits and want the specific silhouette this variant gives you, or if you like the idea of kitbashing across the Hazel family and want another donor kit with unique armor pieces. Skip it if you want one clean standalone Hazel with no shared-mold baggage, the plainer Advanced Hazel or original Hazel kit is the better single purchase. This is a collector's add-on, not an entry point, and it rewards people who already know the AOZ story and want to see it on a shelf in this specific pose.

The build story

What the build is actually like, and the engineering worth knowing about.

The core body goes together the same way the Advanced Hazel does, so if you have built that kit the cockpit block, legs, and arms will feel immediately familiar. The new pieces are all in the armor layer, the Owsla-style chest plate, the HRUDUDU II side pack, and the Psycho Blade, and those are where the kit actually earns its price. Gate placement on the shared runners is the same as the earlier release, mostly clean, a few nubs land on visible armor edges.

Weapon loadout is solid for an HG: a composite shield booster, a ray gun, a ray saber, twin cannons, and the long-range Big Wig Cannon derived from the Bi-Zack TR-2, plus the winch cannons built into the side units. That is a genuinely full arsenal for the price band. The weak point is mechanical rather than cosmetic, the joint pinning the HRUDUDU II unit to the side armor uses a shallow dowel that does not hold tension well, so dynamic poses with the side units extended need a light touch or a drop of glue if you do not plan to swap parts later.

Lore & trivia

01The Haze'n-thley-Rah II is a further combat development of the Haze'n-thley, itself considered the ultimate wartime evolution of the original Hazel line in the Advance of Zeta side story.
02Its Big Wig Cannon is derived from the long-range weapon carried by the YRMS-106+BL-85X Bi-Zack TR-2 [Bigwig], tying this kit's armament directly to another suit in the TR series.
03The kit reuses the runner system from the HGUC Advanced Hazel, part of Bandai's deliberate kitbash-friendly design across the AOZ HG line so builders can mix and match parts between Hazel variants.
04This release was Premium Bandai exclusive, sold direct rather than through general retail, which is typical for the more obscure AOZ side-story variants.
