While most itako are partially blind from an early age, Kino was not born blind at all. She lost her vision during World War II and became completely blind. With very few options left, she chose to become an itako. As the level of her spiritual ability rose, she caught the eye of the Asakura family and was later asked to marry Yohmei Asakura, Yoh's grandfather.
Instead of living at the Asakura family home in Izumo, she chooses to live in Shimokita, in the Aomori prefecture, near Osorezan. She runs what is ostensibly a traditional Japanese inn, the "Yasui Ryokan". In reality however, she uses the inn to house her apprentices. When Anna was abandoned as a child, Kino sensed the amount of spiritual power Anna possessed and took her in. Training her as an itako, Kino was impressed by Anna's potential and suggested that she should marry Yoh.
