A fierce demon warrior stands ready for battle, adorned with sharp, curved horns that glint menacingly. Heavy chains drape around its muscular form, each link glowing with a sinister power. Purple flames dance and flicker along its limbs, casting an eerie light across its dark, armored body. Around the demon's head, a surreal aura of pink energy pulses, creating a vivid contrast against the fiery backdrop. The scene is rendered in a dynamic anime and manga style, rich in intricate details and bold, expressive lines, capturing the intense energy and otherworldly presence of the formidable figure.
