From my experience Amakuni is usually associated with Waifu PVC figures which are borderline R18 at times but they do have close ties with Hobby Japan magazine and now they release a heavyweight item for Gaogaigar! I suppose that Genesic Gaogaigar wasn't a fluke. Standing tall on 30 Cm with complete transformation gimmick and partial diecast parts, Amakuni's King J-Der will be scheduled for December 2024 release schedule with 58000 price tag which is kind of expected from non Bandai manufacturer.
No doubt this version of King J-Der outclass the Super minipla version and appear to have somewhat decent articulation too. As expected Sentinel had a part in this massive project and i wonder if the team behind the Gattai Da Garn also had a hand behind this project, if so i hope their work on Mightgaine is not lagging behind. King J-Der is always one of my favorite mecha from Gaogaigar and Yuusha series as it is a dedicated Heavy support mecha that can stand on its own ground admirably well. Another reason I had a soft spot on King J-Der also due to the pilot himself, Soldat-J who once turned villain against the Braves as Zonder, but never forgot his pride as warrior. Once regained his original identity as Soldat J, he remains stoic and continues his fight against greater enemy even if all of his former comrades are long gone already. Apparently King J-Der also made appearance in SRW 30 which i should give a check as well
