Luna Rindou is a klutz who loves to daydream and relies very much on her best friend. Her greatest treasure is an amulet that once belonged to her mother. One day, she runs away only to have the amulet stolen by a boy and girl who turn into animals when they come into possession of the amulet. What is the meaning of this!?

Youkai Navi Luna had two volumes published in English as Fairy Navigator Run by Del Rey from May 25 to October 26, 2010, before the company was acquired by Kodansha USA, who chose not to continue releasing the series.
