[Frost Moon, Yi Yi Ya Ya.
The Nagato Family welcomed a newborn life, a girl named Tsuruko. Nagato Tsuruko was the child of Nagato Saburo and Narukami Haru.
The newly born Nagato Tsuruko had a pair of beautiful big eyes, which she seemed to have inherited from Narukami Haru, for Narukami Haru also had a pair of beautiful big eyes. Later, Nagato Tsuruko heard her father Saburo saying that he was attracted by Narukami Haru's beautiful eyes.
Narukami Haru was originally a Miko apprentice at the Mountain Shrine, destined to take over the shrine. As a Miko, one needed to remain pure, but Narukami Haru eventually united with Nagato Saburo, so when Nagato Tsuruko was five, she thought that the union of her father and mother must be a beautiful story.
However, Nagato Tsuruko overheard from the servants that this beautiful story needed to include the word "difficult."
