Prompt: Masterpiece, ultra-detailed dark fantasy illustration of a terrifying demonic samurai warrior lunging forward in a violent downward sword attack. His face is concealed behind an elaborate polished ivory-gold oni mask with sharp angular cheekbones, intricate swirling engravings, menacing hollow eyes, and a sinister skeletal grin. Wild jet-black hair erupts upward in thick windswept strands.

Wearing magnificent crimson-red and antique-gold samurai armor, with enormous layered shoulder guards, ornate engraved chest plates, intricate golden filigree, overlapping metallic scales, and a massive tattered blood-red cape whipping violently behind him. The armor glitters with molten-gold reflections, while deep black shadows emphasize its intricate sculptural details.

He lunges diagonally toward the viewer, torso twisting aggressively, head lowered, one armored arm raised high behind his shoulder gripping the katana, while his opposite arm extends outward for balance. An enormous curved katana sweeps diagonally across the foreground from upper left to lower right, its brilliant ivory-white blade engulfed in swirling golden flames, decorated with intricate flowing Damascus-like patterns.

Extreme dynamic low-angle three-quarter perspective, dramatic foreshortening of his armored arms, twisting torso, and oversized flaming blade. His masked face dominates the upper center, surrounded by violently flowing crimson fabric, flying embers, and explosive ribbons of white-gold fire.

A striking flat ultramarine-blue background contrasts violently with the crimson armor and luminous golden flames. Abstract streaks of burning light form enormous jagged calligraphic shapes across the sky, resembling ancient magical battle sigils rather than readable text.
