From Gundam Build Fighters comes the 1/144 High Grade R-Gyagya released by Bandai. In the anime series this particular mecha was used by Kaoruko Sazaki. I never liked the design of the Gyan, from which this mecha is based, but I have to say that this is a fresh concept that truly impressed me. Aside from the Gyan I thought it had shades of the Jagd Doga but upon checking I found out I was wrong or maybe it was the Sazabi? Hehehe... who cares, just as long as it looks great we shouldn't care about where it got its inspiration from.
The 1/144 High Grade R-Gyagya is selling for $21.99 at Amazon
Construction Manual & Color Guide for the 1/144 High Grade R-Gyagya was translated to English from the Japanese manual posted at Dalong's Gunpla & Model Kit Review site. For the meaning of the symbols found in the model kit's manual, kindly refer to this post.
