The hijutsu, containing all the world's knowledge. The female spirit of the Shinrabanshou, whom Miharu refers to as "Miss Fairy" (Yousei-san), was once a human living in the Sengoku period. She was the first user of the Shinrabanshou. She died during an attacks of the Iga ninjas on her village. However, as the one destined to bind the Shinrabansho to humans, her soul did not pass on, and instead merged with the Shinrabansho and took the form she has today.
