Kanako Ohno is the first female to join Genshiken and she does it of her own free will. Kanaka is a soft-spoken, well-endowed girl who enjoys cosplaying. Her enthusiasm for her hobbies serves as a foil for Saki Kasukabe and later Chika Ogiue, who both resist her attempts to get them involved in club activities.
She has what is known as "oyajicon", meaning that her preference for anime men is that of middle-aged characters. She especially likes the bald men.
She is currently dating Souichirou Tanaka.
