Chika Ogiue reads and creates female-oriented, yaoi dōjinshi and joins Mitsunori Kugayama as Genshiken's other artist. The other female members of Genshiken sometimes call her a "Fujoshi" because of that.

She is a self-professed otaku-hater who feels a deep-seated shame and self-loathing toward her own interests and hobbies. She is deeply ashamed of her otaku nature, but gradually comes to accept it as the series progresses.

Ogiue is currently dating Kanji Sasahara.
