character: original. A cinematic medium shot from a slightly low angle depicts a solemn ritual in a grand gothic cathedral hall. In the center, a long silver-haired incubus boy with pointed ears, curved black horns, and folded membranous bat wings kneels on the marble floor, his arrow-tipped tail curling behind him; he bows his head with a nervous expression, his violet eyes glistening with unshed tears. Standing before him, a tall succubus queen with flowing dark hair and regal horns wears an elaborate shadow-woven gown, her pale hand extended to place a glowing violet sigil-mark or ornate dark collar around the boy's neck. In the background, the Three Vassals watch silently: a masked knight in dark armor with folded arms, a sorceress with floating violet runes at her fingertips, and a slender shadow demon with glowing eyes. The hall features soaring gothic arches, towering candelabras with violet flames, and a glowing magical circle on the floor. Dramatic chiaroscuro lighting blends silver moonlight from stained-glass windows with a violet magical glow, creating a melancholic, solemn atmosphere.
