Traveling back in time, Saigyouji Hanyu finds himself in the Heian Period, a thousand years ago. The dog demons of the west are just beginning to rise, the raccoon cats of Shikoku are emerging, the flower demons of Izumo dominate the Tono region, and the Onmyoji of Heian-kyō aspire to overthrow both the Yin and Yang worlds... His father is the sorcerer who sealed the Saigyou demons, his sister is Saigyouji Yuyuko, he has a mentor, Kamo Tadayuki, and his senior is the Onmyoji Abe Haruaki. To seal the Saigyou demons, Saigyouji Hanyu, who originally wanted a simple life, embarks on the journey to become an Onmyoji, but his life gradually begins to fall apart... This is the story of an Onmyoji, his encounter with Gensokyo, and a young girl.

After Wen Yao arrived in the Hell of Gensokyo, Shiki-sama's daily life became like this: In a singularity, discussing the meaning of death with Ereshkigal, the goddess of the underworld; Izanami, the goddess of the underworld, confiding in someone about her loneliness in a broken world; exploring souls and the abyss with Ash (primarily Gensokyo)... Primarily Gensokyo, interspersed with other worlds, the narrative will likely not follow the above pattern. A mix of first and second settings, the setting is not rigorous (updates will be irregular for now; daily updates will resume after the previous main story is completed; I will try to maintain uninterrupted updates during holidays). PS: If Shiki fans can't find any Shiki-sama fanfiction, they'll have to write their own. PS: I'm bad at creating summaries; this is not the final version.
