Description
Medama Oyaji began existence as Gegerō, a full-bodied adult of the Ghost Tribe. Afflicted by an incurable "melting disease" that decayed his body, he became dependent on bandages. While secluded with his pregnant wife Iwako, he sold his blood for income, unknowingly causing transfusion recipients to take on ghostly appearances. Both he and Iwako eventually perished from illness. After burial, Gegerō focused his spirit into his last intact body part—his eyeball—emerging as an anthropomorphic being with an eyeball head and a diminutive body. This rebirth coincided with the posthumous birth of his son Kitarō from Iwako's grave three days after her burial.
Physically, Medama Oyaji manifests as a miniature humanoid whose head is a single giant eyeball, typically lacking visible hair or clothing. This eyeball features a red iris and a pupil that shifts into a U-shape during sleep, concealing a small mouth beneath. While early adaptations rarely showed him eating, later media depicts him consuming items like cherries, plums, morning dew, and fish eye soup, occasionally revealing a full belly. He possesses regenerative capabilities, recovering from physical damage such as crushing or deep-frying. His size is consistently noted as "tinier than tiny," contrasting his "massive spirit."
His primary role is supporting Kitarō as both father and advisor. He leverages encyclopedic knowledge of yōkai gained during pre-rebirth travels, covering their behaviors, weaknesses, and occult subjects like Akuma or Ancient Inca lore. Connections with figures like Enma-Daiō, ruler of the afterlife, grant him and Kitarō access to supernatural realms. His abilities include detaching his eyeball for reconnaissance, manipulating his body shape, and substituting his eyeball into objects or sockets.
Key personality traits include a calm demeanor in crisis, fierce loyalty especially to Kitarō, and a fondness for cleanliness. He frequently bathes in small containers like teacups or bowls, sometimes using liquids such as sake, cola, or black tea. He enjoys sake and possesses sentimental items like a silk hat gifted by English demons. His catchphrases include exclamations like "Oi! Kitarō!" and expressions of bath-time contentment.
Adaptations largely maintain his backstory, though details like his human era vary (e.g., early 1960s vs. Edo period in films). The 2018 anime depicted his pre-disease human form as gray-haired with one eye covered, resembling Kitarō. Later series expanded his characteristics, showing increased eating or possessing bronchial features like sneezing. His familial bonds extend beyond Kitarō to Iwako (deceased wife), Yuki-Hime (acknowledged as a sister in museum exhibits), and relatives like Kemedama in spin-offs.
