UtsunoMiko (宇宙皇子), also written Utsu no Miko, is a Japanese historical fantasy light novel series written by Keisuke Fujikawa (藤川桂介) and illustrated by Mutsumi Inomata, which was later adapted into an anime of the same title.

The founder of the Shūgendō tradition, the miracle-worker and mountain hermit En no Gyōja, earthly incarnation of the heavenly Jinben Daibosatsu, raised the child as his disciple and named him Utsunomiko, or 'Divine Child of the Heavens', telling Miko that his horn symbolizes the union of heaven and earth, and that his father is Hoku-Ten, the god of the North Star, whose name is Ama no Minaka Nushi no Kami, the primeval creator deity of the Kojiki.

Miko matured in the wilderness and becoming a Yamabushi, learning his master's syncretism of Daoism, Buddhism and Shintoism, and soon started venturing into villages out of curiosity.

He found that the common people of the villages live in poverty and suffering, and began using his spiritual powers to help them.

But his anger at the self-serving rulers and their petty power-struggles grew until he came into open conflict with the Imperial Court (but not the Emperors and the Imperial Family itself, as he befriended some of its members, such as Otsu-no-Miko, a prince of Emperor Tenmu, who, historically, was set up and killed by Empress Jitō in order to secure her son's position as Crown Prince), especially Fujiwara no Fuhito, setting Miko down a long path as a champion of the oppressed, and of his perillious spiritual journey.
