Nyo-ko born as daughter of a daimyo and her parents had gone to great trouble to teach her refined graces. In 1357 the shogun Matasuuri Nagahide planned her marriage with Funada Mitsuhide of far Nakamaru to solidify the relations between the shogun’s extended family and Nyo-ko's father. Nyo-ko however had become the target of an ikiryo. The ikiryo was unconsciously generated by the second wife of Mitsuhide Kei-ko
Nyo-ko was a demure and delicate girl, totally capturing the heart of her husband, Lord Mitsuhide, for the moment. She was skilled in singing and poetry.
