High-End Anime Dark Fantasy Cerberus Battle

High-quality anime. Movie-class, cinematic moonlit dark fantasy sword-fighting anime. A high-density 2D hand-drawn anime battle scene where the character from the reference image fights a giant three-headed black Cerberus that breathes hellfire. The reference image is the primary guide for character identity, face, eye shape, iris color, contour, cheeks, jaw, age, skin tone, hairstyle, hair color, bangs, clothing, decorations, physique, silhouette, atmosphere, unique motifs, and character color. Refer to the character in the reference image and maintain them as the same person throughout. Use the reference image only for character design and world-building; do not reproduce the background, room, furniture, text, UI, settings sheet, white background, pose, angle of view, camera distance, or framing from the image itself. Only expressions, gaze, mouth movements, posture, breathing, and natural movement of hair and clothing during combat may vary. Prohibited: mixed features, generic AI faces, changing person/hairstyle/hair color/clothing/physique/age, cloning, or extra people. [Automatic adjustment to reference character] Fix only the narrative structure: a moonlit flower field, fire starting from a single central bloom, a three-headed Cerberus, a duel with a single Japanese sword, and the moment just before the final clash. Naturally adapt the background plants, props, decorations, flame color, moonlight, reflections, smoke, ash, particles, butterflies, petals, crystals, and sword decorations based on the character's colors and theme. Prohibited: thick outlines, simplified TV anime styles, low-density backgrounds, flat cel shading, smooth CG, 3D textures, or semi-realistic styles. [Cerberus] A giant three-headed black wolf-like beast with sharp fangs, glowing eyes, and a muscular body. [Fixed Scene] Start in a moonlit flower field. A single pale hellfire starts in the center, spreading outward in rings as flowers carbonize. Cerberus emerges from the ring of fire. The character steps in low, using a single katana, deflecting the beast's claws. The battle ends just as the final strike is about to land in a slow-motion hold. [Sound] Ambient sounds: crackling hellfire, crumbling petals, wind, low growls, the sound of claws tearing the ground, and the sharp sound of a sword cutting the air. No dialogue, narration, or singing.
