Dr. Mizuno, a neurologist at the Jounan University Hospital who examined Aya, told Aya's mother, Shioka, that her disease was thought to be spinocerebellar degeneration. This disease causes the cerebellum to atrophy for some reason and the nerve cells in the cerebellum break down, making it increasingly difficult for her to move her body.
