闇の三重奏

Three original characters stand side by side in a dramatic team pose within the dimly lit interior of a dark fantasy castle. In the center is a silver-haired female demon queen with long flowing white hair, piercing red eyes, black and purple curved horns, and a black crown. She wears revealing black and gold bikini armor, black thighhigh boots with gold trim, and a flowing red cape, gripping a large glowing red staff crackling with crimson lightning. To her left is an imposing armored dark knight in full black plate armor with a horned helmet and red glowing eyes, his massive greatsword emitting red energy and black lightning effects. To her right is a male assassin in a dark hooded cloak with his face covered by a black mask, intense red eyes visible, holding twin daggers in a combat-ready pose. The background features gothic stone architecture illuminated by eerie red moonlight streaming through arched windows, with dramatic chiaroscuro lighting casting long shadows and creating an epic, cinematic atmosphere in a detailed anime illustration style.
