Based on the original Frame Arms line, Frame Arms Girl features the robots from that line portrayed as anthropomorphic girls, known as F.A.

The line was designed by Humikane Shimada, based on Takayuki Yanase original mech designs.
The anime adaptation follows a girl named Ao Gennai who is sent a prototype F.A. Girl known as Gourai and is tasked with helping her gather data on both battle and emotions. The two soon encounter more F.A. Girls, who Gourai battles against while also having various adventures alongside.
