Together with HG Ryujinmaru. It's gotten quite a bit bigger.

Together with the Ryuomaru from the Mashin Sozoden series.

This kit is the Ryuomaru released as part of the Wataru HG series. Previously, HG Amplified IMGN Ryuomaruand Mashin Sozoden series Ryuomaruwere released, and now the original Ryuomaru has come out under the HG label. So while multiple versions have been released under the same name, the product name is identical — "Ryuomaru" — which makes things a bit confusing. It's kind of unavoidable given the nature of the Wataru series, so you'll want to pay close attention to the grade label when picking one up.

First off, the quality is quite high, living up to the HG label. Despite the short-limbed proportions, the articulation is solid, and the joints feel smooth yet sturdy. Weapons-wise, it comes with the Chosun and the Bongryonggum — you can store the Bongryonggum inside the Chosun, or mount the Chosun on the back, which is a nice gimmick. Dedicated transformation parts are also included, so you can pull off the Bongwang form transformation smoothly.

On top of that, there are little extras like being able to choose between 2 types of head decorations, or detaching and launching the shoulder claws. It actually boasts a notch higher quality and a more satisfying sense of volume than the already well-received HG Ryujinmaru.It boasts a notch higher quality and a more satisfying sense of volume.

All in all, this is a Wataru kit that turned out better than expected, and it's a real hidden gem that any Wataru fan should absolutely pick up. The proportions might be a bit divisive if you're not familiar with the source material, but if the style sparks your curiosity, it's definitely worth giving a shot. :-)
