Kocchi operates within a barbershop setting, centering his daily existence on professional hairstyling where he displays notable expertise. He forms one of three small, benevolent supernatural entities from Japanese folklore, residing alongside humans in a neighborhood and engaging primarily in harmless mischief rather than frightening hauntings. His companions include Acchi, who dwells in a restaurant attic and pursues cooking, and Socchi, who attends a human school and exhibits a strong affinity for sweets. The trio navigates their environment using ghostly abilities like flight and intangibility, interacting with neighbors and sparking comedic incidents. Their shared experiences involve playful neighborhood explorations, encounters with humans and fellow supernatural beings, and episodic adventures emphasizing camaraderie and lighthearted discovery.
