Yumiko is T�ka's mother and the daughter of Kiyoharu. She is a novelist and her writings usually have a supernatural effect over the land. She has a very childish personality which causes problems for her maid, Nene. Her attitude is very erotic as she often walks around nude and sometimes molests T�ka or Momoka. She is the current host for the goddess Juna. Due to mental scars caused by her traumatic childhood, Yumiko is unable to live normally without the presence of Juna.
