Kameko works at Uma no Hone, a comic shop, where she's earned her nickname thanks to the camera she's practically glued to—she photographs pretty much anything that catches her eye. The irony isn't lost on fans: despite being obsessed with taking pictures, she absolutely hates being photographed herself and tends to keep her distance from people.
She's petite and flat-chested, with wavy hair that she deliberately covers up under an oversized hat. The hat's become pretty iconic at this point—she's clearly self-conscious about her appearance and prefers staying under the radar.
