Kashou no Tsuki: Aki Kyougen

A resident of the Floating Castle that battle demon beings, the girl Rasutel (Rasu), chosen by the willful lady, the Demon-Breaker sword, is sent on a quest to save a princess kidnapped by a Youki. Her quest is helped by a mysterious Youki called Anshu (but he has basic color that usual Youkis do not have.... hehe!). She is also hampered in her quest by her demon-being oriented younger brother who seeks her golden eyes, the heritage of their father, the Golden Youshu.

Fuzuchi Kuraki is a quiet young high school student blessed with immense psychic powers and an ancient sword. He is searching for other magical artifacts with the help of Nanachi Takeo, a college student with latent powers of his own. They delve deep into the dark magic of Izumo, only to discover the secrets buried within the birthplace of all Japanese mythology.

Whisked away to the land of Kyou, Akane learns that she is the Ryuujin no Miko, and meets the Hachiyou, her protectors. They must defeat Akuram, a demon who wants to destroy Kyou using the power of Azusa, a woman who has the power to absorb human energy. If Akane and the Hachiyou cannot defeat Akuram and bring peace to Kyou, Azusa'a power will destroy the humans.
