Mirei Yajima

Yajima is a first-year female student who also decided to join Genshiken after seeing Ogiue's manga poster drawing demonstration. She too is a fujoshi, though not as blatant about it as Yoshitake. She is of stocky build and tends to wear men's clothing. She has a very hard time accepting Hato's cross-dressing even though she knows the whole story behind it and routinely tells him to stop it. Yajima is also one of Ogiue's paid assistants on Ogiue's professional manga, doing the erasing of pencil lines and general page cleanup.
