Kitarou, the last living member of the Ghost Tribe, entered the world under supernatural circumstances: born after his pregnant mother Iwako died and was buried, he crawled independently from the grave three days later as a misshapen infant. His father, originally a full Ghost Tribe member, perished from disease but reincarnated as Medama-Oyaji, a sentient eyeball residing within Kitarou's empty left eye socket and accompanying him constantly. Physically resembling a young boy, Kitarou stands approximately 130 centimeters tall and weighs around 30 kilograms. His most distinctive feature is the absent left eye, typically concealed by his long hair, depicted as silver in early versions and brown in later adaptations. He wears a black-and-yellow striped vest (chanchanko) over a navy blue Showa-era school uniform, paired with wooden geta sandals; these garments possess supernatural properties including durability and flight capability. Kitarou's age varies significantly across media. Early stories place his birth in 1954, showing him attending elementary school in 1961. Conversely, other adaptations establish him as centuries old, referencing activities during Japan's Edo period and live-action films confirming his age as 350 years. This extended lifespan stems from his yokai heritage, though a half-human lineage is occasionally suggested but rarely explored. His primary mission involves mediating conflicts between humans and yokai, protecting humans from malicious entities while advocating for coexistence. This contrasts sharply with his initial portrayal in *Hakaba Kitarou*, where he exhibited mischievous, self-serving tendencies, displaying indifference to human suffering and material greed. Typically operating from GeGeGe Forest, he lives in poverty within a treehouse or transient dwellings like yokai apartments, frequently declining monetary rewards for his services. Kitarou possesses abilities including firing hair needles as projectiles, generating electrical charges from his fingers, sensing supernatural activity through a hair antenna, and rapid regeneration from injuries. Key artifacts are his Remote Control Geta, enabling flight and autonomous movement, and a Yokai Ocarina used for communication or control. He maintains a low profile in human society, though spin-offs like *Zoku GeGeGe no Kitarou* explore his adolescence and attempts at part-time jobs. Relationships define several storylines: Medama-Oyaji serves as both advisor and comic relief, offering extensive yokai lore knowledge. He maintains a contentious partnership with Nezumi-Otoko, a half-rat yokai known for cowardice and greed, and a protective bond with Neko-Musume, a catgirl half-yokai. Ancillary materials expand his family, introducing Yuki-Hime as his sister and Mary as his wife, with an unborn son destined for his soul reincarnation. His adventures frequently involve confronting non-Japanese entities like Dracula or Chinese vampires alongside traditional yokai threats. Stories such as *The Great Yokai War* draw direct parallels to Japanese folktales like Momotaro, emphasizing cultural defense against foreign supernatural incursions. A core thematic element involves the visibility of yokai, dependent on human belief; Kitarou can manipulate this perception to remain hidden or revealed.
