Heian period. The night is dark and the wind is high, in an old-fashioned day house. A young man in a loose brown robe, with a pair of dead fish eyes hanging from his head, sat in front of a pale and frail child with a stiff smile. "Sanyashiki-sama." The young man addressed the child in front of him. The child, with long hair and a pale and sickly complexion, was called "Maternity Houseshiki" and looked at the young man with a hideous face. The moonlight shone into the house through the courtyard, illuminating the child's gradually demonic pupils, like red flowers on the other side. Although the young man in the brown robe ignored and looked calm. But his trembling hands, hidden under his sleeves, revealed his thoughts. Cold sweat oozed from the young man's back. This Heian era, what's wrong!!
