Eri Aikawa (相川 絵理, Aikawa Eri) is a supporting character in the Junjou Romantica series. She is Akihiko Usami's editor with Marukawa Publishing, as well as a friend to both him and Misaki Takahashi. As Usami's editor, Aikawa is constantly pushing him to finish his work on time. On the outside, she seems like a well-mannered and kind professional, but when Usami does not hand in his manuscripts on time she is famous for freaking out and even, on one occasion, attacking him.
