Another of Ogiue's friends from junior high school, Shigeta (distinguished by her blushing cheeks) was one of the group with whom Ogiue made dōjinshi. While perhaps not directly responsible for the incident involving Ogiue and Makita, she still associates with Nakajima even five years later, and her presence is enough to upset Ogiue at Comifes when she appears. Her name is not mentioned in the manga, or in dialogue; it appears in the credits in episode 11 of Genshiken 2.
