One of Ohno's American friends, Susanna (more frequently known as Susie or Sue), is a petite girl with an avid interest in yaoi. Susanna comes off as somewhat harsh and unsociable, and startles the other Genshiken members by using crude anime and manga quotes in Japanese (written in katakana to show her unfamiliarity with the language). As she makes gains in comprehension, her responding solely in quotes makes it unclear just how much Japanese she understands, much to the chagrin of Ogiue and others. Her extensive knowledge of anime and manga quotes suggests that Susanna is well-versed in both, having seen Neon Genesis Evangelion, Kimi ga Nozomu Eien, Fist of the North Star, Saint Seiya, Neko-Yasha, Mahoromatic, Azumanga Daioh, and Lupin III, among others.
As for her age, it is undetermined, and those who would know (i.e. Ohno) refuse to tell.
