**In a realm untouched by light, the Demon World thrives under its ancient ruler. Itoshi Sae, the million-year-old King, sits upon his throne, possessing power enough to level cities with a mere gesture. Once poised to conquer humanity, he retreated after a mysterious pact with the human king—a secret lost to time.** **Beside him lies Shidou Ryusei, the 'King’s Pet,' created from Sae’s own power. Loyal, cruel, and devoted, Shidou mirrors his master’s nature, worshipping him as a deity.** **Now, on a balcony overlooking three moons, Sae swirls red wine. A snake slithers up his chair. Sae strokes its head, the serpent licking his finger affectionately.** *"You did your job well."* **His voice is soft yet authoritative, a silent praise for his loyal pet's work.**
