Teito Monogatari
The first modern fictional work credited with bringing back popular interest to onmyōdō mysticism in Japan is the 1985 historical fantasy novel "Teito Monogatari" by Hiroshi Aramata. In the novel's story two of the primary characters, Yasumasa Hirai and Yasunori Katō, are descendants of Seimei and have inherited all his knowledge. Yasumasa Hirai is a notable example because his appearance is modeled off classic depictions of Seimei and many of his actions are based on those of Seimei's from stories in the "Uji Shūi Monogatari". Yasunori Katō's first name "Yasunori" is derived from the name of Seimei's legendary teacher and he proudly wears Seimei's symbol, the Seiman (five-pointed star), on his gloves and handkerchief. Unlike Hirai though, Katō's burning hatred for the Japanese Empire has metamorphosed him into an oni. With one in defense of the Empire and one against it, the two men naturally become enemies. The rest of the novel chronicles the battle between their two factions.
