Dark Ronin Swordsman Anime Action AI Image Prompt

Create a dark, hyper-detailed anime action illustration in a wide cinematic 16:9 frame. Show {argument name="character name" default="a fierce ronin swordsman"} in the center, lunging forward through chaos with a katana held diagonally across the image from the left foreground toward the lower right foreground. The character has {argument name="hair style" default="wild long black hair exploding outward in thick tangled strands"}, pale shadowed skin, an intense glare with {argument name="eye color" default="glowing red eyes"}, and a black tattered robe or cloak that blends into the surrounding ink. The katana should be the dominant visual element: a long polished blade with a thin bright white edge and red reflected glow, ornate dark hilt visible on the left side, cutting through splashes and motion lines. Surround the figure with violent abstract black ink tendrils, chaotic brush strokes, and {argument name="splash color" default="crimson red blood-like splatter"} bursting across the whole canvas; include exactly one swordsman, one katana, and one central face visible through the darkness. Use a gritty manga-cover style with extreme contrast, dense linework, speed lines, painterly ink textures, horror-action energy, and a limited palette of black, deep red, gray, off-white, and small bright highlights. Background should be an abstract storm of black and red splashes on a dirty parchment-gray field, with no readable text, no logo, no border, and no extra characters.
