1955. Kitaro's father, Medama Oyaji, comes to Yagura Village in search of his missing wife. The village was ruled by the Ryuga clan, which controls Japan's political and business circles behind the scenes. Mizuki, who works at a blood bank, visits the village with a secret mission to mourn the death of the head of his family, and meets Kitaro's father. While an ugly fight unfolds over the succession of the head of the family, a member of the family is brutally murdered at the village shrine. It was the beginning of a terrifying chain of events.
Unfortunately the movie The Birth of Kitaro: The Mystery of GeGeGe is not yet available on HBO Max.
