* Based on Kotobukiya's Frame Arms Girl model kit line. Gennai Ao mistakenly opens a package that wasn't meant for her, and, to her surprise, she sees a small robot named Gourai, a Frame Arms Girl who has an evolving personality. Confused as to how this little robot made it into her life, she finds out that she is the first person to activate her. She realizes taking care of Gourai is harder than she thought, especially when competitive fights are involved! Source: animenetwork
