Beyond Atlantica, history and legend:
Nōhime (濃姫?) also Kichō (帰蝶) or Lady/Princess Noh, was the
wife of Oda Nobunaga, a major daimyo during the Sengoku period of Japanese history. Her proper name was Kichō, but since she came from Mino Province, she is most commonly referred to as Nōhime (Princess of Mino). She was renowned for her
beauty and cleverness.
Nōhime's father was the daimyo Saitō Dōsan and her mother was known as Omi no Kata. Nōhime herself appears very little in any historical record, and there is not a lot of information on the dates of her birth or death; however, proposed dates for her birth fall between 1533–1535.

It was alleged that Nōhime was acting as a spy, or even assassin, for her father; at that time it was not an uncommon practice for a wife to relay information to her maiden family. Given Nobunaga's reputation at the time as the unruly "Fool of Owari" (Owari no Utsuke 尾張の虚け), it was also not impossible for Dōsan to want Nōhime to assassinate him as she was skilled in both the sword and a selection of martial arts.
