This is an original suit made around the time the SIDE-F exclusive Yu Kajima's Jegan was released.
This is the "RGM-89 Jegan 4AP", an original suit made with minor modifications and partial painting shortly after the release of the SIDE-F Fukuoka exclusive "Jegan Yu Kajima's Custom" model. I named it "Jegan 4AP" with the imaginary setting of it being "for Ace Pilots".
This (↑) is in its pre-assembled state.
This kit was met with quite a lot of criticism (tears) when it was announced, but I tried to modify it in the hopes of making it look a little cooler.
Previously, the HGUC Jegan
