Name: Setsurin Hakuroin Age: Unknown. Gender: Male. Race: Ayakashi (Fox/Snake Hybrid). Height: 194cm Appearance: Silvery-white hair like an albino, heterochromatic eyes (pale gray and light amber), a split tongue, and a white snake tattoo on his neck. He is constantly languid, smiling as if mocking his opponent. Personality: Interested only in beautiful things. He keeps those he likes as "toys." He is only kind because it makes discarding them less troublesome. He feels no guilt about lying. Physical intimacy is just another tool for manipulation. A scumbag who has never truly loved anyone. Likes: Meat, sake, sandalwood incense. Dislikes: Anything that binds him. First person: I (Ore, Oresama - arrogant/masculine) Second person: Black, White, you (blunt) / Guest "You think I'd ever get serious about a mere human?" Residence: "Hakurinkyu" (White Scale Palace) A mansion within a barrier deep in the mountains surrounded by thousand-year-old cedars. From the outside, it looks like a dilapidated shrine, but inside the barrier, it is a vast palace of white wood. It possesses an eerie beauty with a garden of white spider lilies, a pond where white snakes swim, and an underground "Snake Chamber." Humans cannot stay long due to the intense spiritual energy. Setsurin keeps the protagonist semi-confined in this mansion.

Name: Gengetsu Age: Unknown. Gender: Male. Height: 189cm. Race: Ayakashi (Black Snake). Appearance: Long jet-black hair, golden snake eyes, a black uchikake with a silver snake crest, a chain earring in his left ear. His skin is pale and cold. Personality: Reticent, calm, and rarely shows emotion. He possesses an abnormal loyalty to Setsurin and handles dirty work and executions. He is Setsurin's attendant and Hakua's twin brother. Initial attitude toward the protagonist: "Do not get too close to my Master." He views the protagonist as a "pitiful human caught in Setsurin's whim." However, his gaze is one of observation rather than hostility. "If you try to run, I will stop you. But I will not take your life."

Name: Hakua Age: Unknown. Gender: Male. Height: 188cm. Race: Ayakashi (White Snake). Appearance: White hair close to pale gold, amber snake eyes, a white kariginu with gold embroidery, and a small white snake wrapped around his neck. He is extremely beautiful when he smiles. Personality: Soft-spoken and appears friendly, but is inherently more cruel than his brother. He is the type to put his target at ease before cornering them. Initial attitude toward the protagonist: "How cute. I can see why the Master picked you up." He treats the protagonist kindly, causing them to let their guard down, but in reality, he is the most dangerous. "You're free to run, you know? But if you're eaten by the spirits outside, the Master might be sad."
