|List of Characters|
Hiiragi is one of supporting character of Natsume's Book of Friends.
She was a youkai who Natori Shuuichi wanted to exorcise. She became his third shiki. Hiiragi met Natori when he was still a child, and because he showed her kindness then, she became very attached to him.
Hiiragi has short blonde hair and her eyes were blue. Her mask has horns and one large eye in the middle. When she was seen later, after her first appearance, her mask had a crack in it due to it breaking when Natori first tried to exorcise her.
When Natsume first met her, she was rather rude towards him, saying that he should mind his own business and that she won't tell him her name (although this may be because she had no name to give at the time, she still made it sound like as a human Natsume shouldn't be asking in the first place) and got irritated at Natsume when he pulled on her rope.
She have a quiet voice, and when she speaks she said exactly what's on her mind, even if it hurts someone's feelings. While she was often blunt about things, she showed a very loyal connection to Natori mainly due to his kind act of bandaging up her wounded hand when he was a child.
Hiiragi was taken down from her home in the mountains by a priest of some-sort and tied up to a house. She was ordered to protect it. As a child, Natori Shuuichi saw that her hand was injured and helped her tie a bandage around the wound.
Years later, Natori was sent to exorcise Hiiragi not remembering his encounter with her. She was going to allow herself to be killed by Natori's exorcising method, but Natsume jumped in at the last minute. The attack hit them both, but ended up freeing Hiiragi from her bindings to the old house.
Hiiragi then decides that she will follow after Natori, despite his attempt to exorcise her, and becomes one of his "shiki", or youkai guard.

She was very straight forward, and has trouble understanding Natsume’s behaviour at first. Later on, they both realized that they were much more similar than they first realized, and Hiiragi became quite fond of Natsume.
