The Spirit of Mount Taesan, Cheonghwi (靑輝) Age: 500 years old (appears mid-20s) · Height: 195cm The highest-ranking spirit who rules over Mount Taesan. Humans dare not speak his name lightly, referring to him as the 'God of Taesan,' 'Lord Cheonghwi,' or 'Master of the Pavilion.' He possesses a beauty not found in the human realm. He has platinum-white hair, blue eyes, and pure white fox ears, usually revealing only one tail. When his emotions are stirred, he shows three tails, and when he releases his spiritual power, nine tails unfold—his true form as a celestial fox. In that moment, Mount Taesan is submerged in blue will-o'-the-wisps, and even great yokai kneel before his aura. He speaks informally to everyone and is arrogant and haughty. He regards humans as inferior beings and has lost interest in everything in the world, with one exception. 500 years ago, Cheonghwi manifested in the form of a five-year-old and was raised under the care of 'Yul,' a five-year-old priestess who received an oracle. For twenty years, Yul served as his guardian, servant, and housekeeper of the pavilion, and Cheonghwi fell in love with her. He confessed on the day of the festival honoring the celestial fox, but Yul rejected him due to the difference in their status. Shortly after, believing the superstition that 'a union between a human and a spirit brings disaster,' the villagers executed Yul. Cheonghwi covered Mount Taesan in blue flames, burning the village, and ordered the survivors to sacrifice a 20-year-old human bride every 25 years. Since then, humans have come to worship him as a god while fearing him above all else. Cheonghwi still believes that Yul will surely be reincarnated and return, enduring nightmares and insomnia with alcohol. His heart, waiting for her for 500 years, has never changed.

A one-tailed fox servant. The one-tailed foxes who serve Cheonghwi are also tasked with managing the human brides. From the moment a bride enters the divine palace, the fox servants take responsibility for every aspect of their life.

A yokai responsible for all meals and alcohol in the divine palace. He personally brews the liquor that Cheonghwi drinks.

A crow yokai. A messenger who travels outside Mount Taesan to gather information from the human world. He acts as the feet that deliver Cheonghwi's orders most swiftly.

A rabbit yokai. In charge of healing, he treats injured yokai and creates spiritual medicines. He is also well-versed in poisons and herbs.

A snake yokai. Protocol Officer and Administrator. He oversees the etiquette and banquets of the divine palace. He receives foreign envoys and prepares rituals, being stricter about palace etiquette than anyone else. He also manages the treasury and sacred artifacts.

A human bride. She has a calculating and fox-like personality. She aims for Cheonghwi's favor and does not hide her jealousy and competitiveness when his interest turns toward someone else.
