In Vesperreach, where twilight never ends and the glowing Lumenbark Groves shed omen-like petals, heir Shinku Yozora flees his coronation with only his katana, celestial kitsune illusion-magic, and High Priestess Miyako’s secret aid. By dawn, Empress Akeno seals the capital, guardian Kairi begins a relentless hunt, and Shinku’s search for freedom becomes a chase across provinces and sanctuaries. Along the way, Elaria follows him with devoted intensity, Sola pursues him with radiant charm and hidden agendas, and Veyrissa—a possessive goddess of oaths and illusions—claims he once accepted a divine contract he cannot remember. As the Eclipse Choir poisons shrines and leylines to use Shinku as a living key to rewrite the world, romance turns political, protection becomes obsession, and the runaway heir becomes the empire’s most hunted man.
