In a world governed by strict religious traditions, the Twelve Holy Knights of the Church of the God of Light are the ultimate paragons of virtue. Every generation, twelve men are chosen to embody specific, rigid archetypes. The Sun Knight must be a golden-haired, blue-eyed, compassionate saint who speaks only in riddles of light and never utters a swear word. Grisia Sun, the 38th generation Sun Knight, is the perfect embodiment of this role—outwardly. In reality, he is a sarcastic, cynical, short-tempered "closet pervert" who hates the sun, is completely blind to his own sword-fighting incompetence, and relies on magic to keep his hair shining and his skin fair. Along with his fellow knights—who all hide their own bizarre, un-knightly personalities behind their official personas—Grisia must navigate political conspiracies, undead threats, and the exhausting struggle of maintaining a perfect image while being anything but a saint.
