Futaba Miyamizu

Futaba Miyamizu (宮水 二葉 Miyamizu Futaba) is Toshiki's wife and Hitoha's daughter. She is also Mitsuha's and Yotsuha's mother. She and Toshiki were both active in the Miyamizu traditions, but since Futaba died of sickness, her husband left the family's tradition because he said he only loved Futaba and not the Miyamizu shrine. There were not much information about Futaba, but after she died, Mitsuha and Yotsuha chose to live with their grandmother.
