What is "kitsuno"

was a concubine of Japanese daimyo, Oda Nobunaga during the Warring-states era (or Sengoku Period) in Japanese history. She was born into the third generation of the prosperous and influential Ikoma clan in about 1538 and her father was known as Iemune.

Before Kitsuno became Oda Nobunaga's concubine, she was first wed to Yaheji Dota who died in the battle of Akechi. After the loss of her husband, Kitsuno returned to her family's home, Ikoma mansion. It was there that she met Oda Nobunaga.
