An ultra-giant black coffin, 3 to 4 times the height of the woman, placed in the foreground. A heavy black iron coffin with thick metal armor, aged metal, a scarred surface, Gothic decorations, and metal cross ornaments. The entire coffin is sealed with multiple thick black iron chains, with the lid slightly open, revealing complete darkness inside and a single eerie red eye peering out from the gap, without revealing its identity. A single thick long chain is connected to the coffin; the woman is gripping the chain tightly with both hands, swinging it with her whole body. She swings the giant coffin using the centrifugal force of the chain, using the coffin itself as the striking part of a giant flail. The giant chain draws a large arc around the woman, swirling at high speed through the air with intense centrifugal force; her hair and skirt flutter violently due to the centrifugal force and wind pressure. The giant coffin flies violently toward the foreground, depicted as extremely large, occupying more than half of the screen, while the woman is placed small in the background, creating an extreme size difference between the person and the weapon. Ultra-wide angle, low angle, extreme perspective, intense foreshortening, a composition where the coffin approaches the camera, dynamic action composition. The giant coffin passes at high speed just above the ground, its corners scraping the ground, producing a large amount of vivid orange sparks, intense metal friction, and long trails of sparks. The ground shatters from the impact, with massive amounts of stone fragments, debris, dust, shockwaves, and black smoke flying toward the foreground, emphasizing the overwhelming weight of the giant weapon. Merias wears a black leather bodysuit and high-heel boots, with an open chest and a ruby necklace. Her hair is pearly white with a purplish tint, styled in a swept-back center part, and she has red eyes. Merias is an elegant and noble being with dragon horns, ruby-like eyes with vertical pupils, long ears extending sideways, coquettish dark cherry lips, black nails, and is stylish, cool, and sexy. The moment she is attacking by swinging the ultra-giant coffin like a flail; a giant coffin flail, an abnormally huge weapon. Strong motion blur and arc-shaped afterimages on the chain and coffin, speed lines, and violently fluttering hair and clothing, with an expression that makes the rotational movement immediately apparent. The background contains no specific buildings; it is an abstract space based on white and light gray, with black ink splashes, expressions like splashed sumi ink, rough brush strokes, smoke, dust, and large areas of negative space. Monochromatic tones dominated by white, black, and gray, low saturation, high contrast, with only the vivid orange of the sparks and the single red eye inside the coffin as accent colors.
