Onmyouji(1999)

Must we believe in ancient legends? In mythical tales and characters?

As a child, Abe-no-Seimei in the company of his master Kamo Tadayuki walks his first steps on the paths frequented by evil spirits and angry souls of darkness with a thousand spells. Seimei, who can feel an evil entity approaching before anyone else, is taken in by Tadayuki, who sees in him an exceptional talent for the practices of Yin and Yang.

From that day on, Seimei was made his disciple and was taught all his secrets.
