Shyness Machine Girl (hajiraiマシンガール, Hajirai mashin gāru) was released January 23, 2009 in Japan as part of the Japanese DVD release for The Machine Girl. It is a brief side-story or gaiden to The Machine Girl rather than a direct sequel. This version stars gravure idol Noriko Kijima as Yoshie, who has not only a machine-gun arm but another gun which extends from her lower anatomy.
