In a collaboration between Frame Arms Girl and Kotobukiya's original character Nipako, comes an all-new model kit: Frame Arms Girls Architect (Nipako Ver.). This unit's design is based on the original mech of Architect by Takayuki Yanase which was illustrated by Humikane Shimada. The coloring and additional parts included for this collaborative design are based on designs by VaistarStudio.

Not only is the armor color scheme taken from Nipako, but additional hair parts, headgear, and a new M.S.G. pin vise and hand drill are also included to resemble Nipako. The model kit includes three face parts and five pairs of hands.
