Medama Oyaji is Kitaro's father and one of the series' most distinctive characters—literally just a sentient eyeball with a small body attached. He wasn't always this way; he was once a regular adult until disease killed him, and he ended up reborn from his own decaying remains as this strange, compact creature. Despite his fragile appearance, he's got real backbone and deeply cares about his son. He's basically the family's walking encyclopedia on ghosts and monsters, which makes sense given what he's become. On a lighter note, he's kind of obsessed with cleanliness and is famous for constantly bathing in a tiny bowl—it's probably his most endearing quirk. Fans often note that he represents the heart of the family dynamic, balancing Kitaro's more serious demeanor with genuine warmth.
