Monochrome Combat Storyboard Art

Goal: Create a single ultra-wide cinematic anime storyboard sheet for a high-impact hand-to-hand battle scene, designed as black-and-white visual reference art.

Canvas: 21:9 horizontal canvas, clean white background, thin black outer border, divided into exactly 12 rectangular storyboard panels arranged in a 3-row by 4-column grid with narrow white gutters and thin black panel borders.

Visual style: High-contrast monochrome ink art, characters mostly rendered as solid black silhouettes with minimal white rim highlights, sharp manga/anime speed lines, impact bursts, ink splatter, ground scrape marks, and exaggerated cinematic camera angles. No grayscale shading, no color, no speech bubbles, no captions, no logos, no watermark.

Characters: Two fighters only. Fighter A is {argument name="dominant fighter" default="a tall, extremely muscular male silhouette with spiky hair, sleeveless combat outfit, gloves, loose pants, and heavy boots"}. Fighter B is {argument name="opponent fighter" default="a smaller athletic male silhouette with spiky hair, fitted combat clothes, gloves, and boots"}. Keep both characters as dark silhouettes throughout, with strong readable poses.

Panel layout and action beats: Include exactly 12 panels, left to right, top to bottom:
1. Wide establishing standoff: the large fighter stands powerfully on the left, the smaller fighter squares up on the right, both grounded on rough black brush shadows.
2. Dynamic low-angle charge: the large fighter lunges forward toward camera, fist cocked, strong radial speed lines behind him.
3. Close-up impact punch: the large fighter’s fist smashes into the smaller fighter’s face or upper body, with a bright white impact starburst.
4. Side view knockback: the smaller fighter is thrown backward to the right while the large fighter follows through in a running strike pose.
5. Mid-shot kick impact: the large fighter drives a heavy kick or knee into the smaller fighter, who bends forward from the blow, with burst lines at the torso.
6. Tight close combat: the large fighter grabs or body-checks the opponent at close range, faces close, strong white impact flash between their bodies.
7. Airborne launch: the smaller fighter flies diagonally across an otherwise open white panel, debris and ground slash marks trailing from the launch point.
8. Running punch chase: the large fighter dashes in from the left and lands another straight punch on the opponent at the right edge, with horizontal speed streaks.
9. Ground slam: the large fighter crouches over the opponent and drives him into the ground, huge black splash-like impact lines radiating upward.
10. Downed opponent strike: the smaller fighter lies on the ground while the large fighter stands over him and punches downward, with a compact impact burst.
11. Final power punch: dramatic perspective shot from behind the large fighter as he throws a massive punch into the opponent, surrounded by dense speed lines and impact shards.
12. Aftermath: the large fighter stands tall and victorious on the left; the smaller fighter kneels or collapses on the right with one hand on the ground, defeated.

Constraints: Use {argument name="aspect ratio" default="21:9"}; keep exactly 12 panels and exactly two fighters; make the action read clearly as one continuous brutal anime battle sequence; preserve the clean storyboard-sheet composition; avoid extra characters, weapons, text, color, gore, or background scenery beyond speed lines and ground marks.
