Kagami: two mecha ronin duel a giant of mirror shards

Create a 2D anime short for the web. It must look completely like real Japanese anime, as if it were taken directly from a finished theatrical anime film. This is traditional-looking, hand-drawn 2D anime, not a 3D animation, a moving illustration, or a stylized web graphic.

Deliver a single, self-contained HTML file that plays offline, with a synthesized soundtrack. Use any tools, libraries, references, guides, literally anything etc.

Use theatrical samurai and mecha anime as the art style reference for design, line work, painted backgrounds and colour. The film is 84 seconds long, in 40 shots. Its characters are two rival mecha ronin, SUMI and YUKI, and UTSUSHI, a colossal giant made of mirror shards. No people appear in the film. Use any tools or techniques you want, including 3D, as long as the final result looks 100% like hand-drawn 2D anime.

SCENE
Open on an endless mirror lake at sunset: the sky doubled, two tiny silhouettes far apart. Cut between two worlds. In a neon city canyon at night, in the rain, an armoured foot splashes into a puddle full of pink and cyan signs, and SUMI, a heavy black ronin, walks down the street, his red scarf whipping. On a snowy pass at dawn, a white hand brushes snow off a mossy stone lantern, and YUKI, a slim white ronin, walks down stone steps through a broken red gate above a sea of clouds. His red eye slit glows; her cyan eyes breathe vapour. Omens: Sumi's reflection in a puddle turns to the camera with white eyes for three frames while he walks on; a white crack flickers across Yuki's reflection in frozen ice. She leaps off the cliff into the clouds. Match cut on the foot: his foot lands on the mirror lake and one perfect ripple ring crosses the reflected sunset.
They stop sixty metres apart, side on, the sun exactly between them. His thumb pushes the guard, a sliver of steel flashes; she sinks low and draws two blades in reverse grip. Stillness. One leftover raindrop slides off his scarf, hits the lake, and the camera tilts down into the reflection: under their feet the reflected sky holds a colossal face of mirror shards. Its white eyes open. Both look down.
They charge, meet in two impact frames, pass each other and stab their blades into the mirror at the giant's eye. Silence. Cracks race to the horizon and the giant pushes up into the real sky, glass and water pouring off it. Its shard sword carves a wall of spray as they leap over it. Yuki runs up its arm and cracks its face; a red-gold aura ignites along Sumi's blade as his scarf burns into embers. They leap from opposite sides into the sun and cut a giant X through its chest. One second of nothing. The X splits the clouds for kilometres, and the giant bursts into shards that fall like snow. The lake heals. He sheathes with a click; they bow with the sun between them, and walk away in opposite directions, fading to gold.

ANIME QUALITY STANDARD
Every frame must look drawn by professional anime animators and painted by master background artists.
SUMI: 18 m, broad and slow. Low kabuto, a thin gold crescent crest, dark faceplate with one red eye slit FF3B2E, huge lacquered shoulder guards laced with red cord, a tattered red scarf, a long blade with a gold guard. Lacquer 2C3150, gold C9A24A.
YUKI: 15 m, fast and precise. Sleek white helmet with swept blade crests and a long plume, cyan eyes 5CF2FF, slim waist, vermilion edges D2402F, two short blades at her back. White EEEDF2, lavender shade A9ABD0.
UTSUSHI: 200 m, hundreds of irregular mirror shards with thin dark gaps; each shows the sunset sky, sun-facing shards blaze gold, each carries a crisp glint. Its helmet merges both rivals. Eyes like two white suns.
Line art: Confident hand-inked lines with pressure, on every plate boundary.
Coloring: Clean cel areas, hard cool lavender shadows, crisp highlights. Never murky: night is blue-violet, dawn pink-blue, sunset gold and ultramarine.
Backgrounds: Hand-painted gouache: a dense neon street with real kanji signs; a snowy ridge above a sea of clouds; towering sunset cumulus doubled in a perfect mirror.
Lighting: A painted sun, neon glows, and a character key light so faces always read.
Effects: Bold drawn FX on threes: rain, snow, ripple rings, glass, sparks, slashes, speed lines, inverted ink impact frames. Never particle mush.
Animation: Characters on twos, strong key poses, real holds. Huge things move slowly. Nothing clips, slides or floats.
Sound: Original score and effects timed to the picture: a low bamboo flute for Sumi, koto plucks for Yuki, rain, wind, a far temple bell, heartbeat taiko, a single drop ringing, glass tearing, choir and brass over driving taiko, two real silences, a sheathe click, both motifs together at the end.
Direction: Macro close-ups against huge wide shots, stillness before every strike: tense silence, explosive action, quiet respect.

IT MUST NOT LOOK LIKE
- 3D: No plastic materials, CGI shading, visible polygons or game-engine lighting.
- Blocky shapes: No plain boxes or toy proportions. Every plate has seams, bevels or lacing.
- SVG or vector art: No perfect curves, uniform outlines or basic gradients.
- Web animation: No sliding layers, bobbing, software easing or puppet joints.
- Pasted-on elements: No 2D sprites floating in a 3D scene.
- AI art: No warped shapes, melted details, flicker or changing designs.
- Non-anime art: No Western cartoon designs or realistic rendering.
- Amateur work: No stiff poses, empty backgrounds, muddy colors or placeholders.

You are free to change any part of the prompt, if it would result in better results.

It should feel silent, sharp and enormous.

Before finishing, inspect random frames as still images. If any frame does not look completely like real 2D anime, keep improving it.

Do not stop until every frame could pass as a still from a theatrical anime film.
