Kameki, often referred to as Kameko, is one of the main characters working at the manga bookstore Umanohone. Her most defining trait is her deep and somewhat obsessive passion for photography, as she is almost never seen without a camera in her hands. In terms of personality, Kameki is characterized as being quite shy and introverted, which contrasts with the more overtly eccentric personalities of some of her coworkers. Despite her reserved nature, she is deeply immersed in the otaku culture that surrounds her workplace, sharing in the general enthusiasm for manga and anime.

Her primary role in the story is as a member of the store's eclectic staff, where her love for photography is her main distinguishing hobby. Her interactions with the other employees are shaped by her quiet demeanor. Like many of her colleagues who are known by nicknames such as Sensei, Director, and Fu Girl, Kameki’s relationships are built on daily workplace camaraderie, though the shyness that defines her character can be a barrier to her forming closer bonds or expressing herself openly. Her personal motivations largely revolve around her interests as an otaku, particularly her dedication to photography, which is a central aspect of her identity.

Throughout the series, which focuses more on situational comedy than deep dramatic arcs, Kameki undergoes minimal overt character development, remaining largely true to her established archetype of the shy, camera-wielding girl. Her notable abilities are all tied to her photography; she is an obsessive and dedicated photographer, capturing moments around the store and the electric town where it is located. Her talent with a camera is her primary means of engaging with her passion for otaku culture and the world around her.
