CHARACTER LOCK KAEL VORNE — tall athletic male, mid-20s, deep bronze skin, sharp jaw, silver-white undercut, thin gold chain braided into left side, single gold orbital piercing. Sleeveless dark-teal combat wrap, asymmetrical gold coin-scale pauldron right shoulder, black hakama trousers. Twin curved blades linked by a thin gold chain. Moves rhythmic, circular, performative, grin masking growing desperation. VFX: gold, clean geometry, fine sparkling particles, metallic trails. RIVEN MOSS — gaunt male, mid-30s, ashen-olive skin, long messy ink-black hair with one copper streak, sunken cheeks, jagged smile. Tattered rust-brown wrap coat, wiry exposed arms. Twin hooked kama coated in viscous black-green ink-metal. Moves like a starving predator — hunched, angular, insect-quick direction changes. VFX: black-green, viscous, irregular, hooked crescents, splattering trails dissolving to smoke. WORLD Original canal entertainment district, night. Leaning timber buildings, wooden bridges, amber lanterns mixed with sick green light, rainwater on black cobblestone. A tea-house burns. Laundry lines and paper lanterns overhead, low smoke, drifting ash. One untouched golden lantern glows at the street's far end — the sequence's visual destination. 30s SEQUENCE (premium stylized cinematic 3D animation) 0-4s: Aerial wide over the burning canal; two figures crash through a wall and collide mid-air in a pressure-wave blast. Smash cut to Kael's chain locking tight, his grin; Riven crawling upright through flames. 4-9s: Lateral tracking as they clash — Kael's blade/chain combo, Riven catches both kama, Kael's ankle-chain trick fails when Riven anchors himself into the ground, smiling wider. 9-14s: Riven floods the ground with ink; crescent blades erupt around Kael as he leaps. 360 orbit as his chain redirects five times into a spinning gold cage, shattering every strike — but Riven appears behind him. 14-19s: Vertical collision through a collapsing balcony, mid-air brass-hit impact, gold sparks and black ink burst, both fall through bursting paper lanterns. 19-24s: Side-tracking sprint down the street, trading blows without slowing, laundry lines cut, lanterns destroyed one by one, street darkening toward the last lantern. 24-28s: Riven's rhythm breaks — brutal fast flurry, Kael's chain snaps, one blade lost, Kael retreats to the final lantern, one blade only. 28-30s: Silence. Riven's cross-slash; Kael steps inside it instead of blocking. Weapons cross beside their faces — flash of gold and ink. Freeze on their finishing poses under the last lantern as it flickers out. A broken chain link falls. Cut to black. CAMERA Deliberate choreography: extreme wides for scale, low-angle hero shots, medium-wide during combat for readability, orbital move during the ink trap, vertical tracking on the rooftop fall, side-tracking on the street run, brief speed ramps on major impacts. No shaky handheld, no chaotic spin — spatial relationship between fighters always clear. CONTINUITY Kael and Riven's faces, proportions, hair, costumes, weapons, and scale stay fixed throughout. Kael carries his chained blades until the chain breaks at ~26s. Riven always carries two kama. No costume regeneration between shots, no facial drift, believable anatomy in every pose. AUDIO Diegetic only — taiko heartbeat, fire roar, timber cracking, chain tension, metal-on-metal, brass hit at 14s, silence before the final blow. No music with lyrics, no dialogue, no voiceover. NEGATIVE Two original characters only — no existing anime likeness, no Demon Slayer characters/uniforms/markings, no canon hairstyles or weapons, no franchise insignia. No extra characters, no crowd combat, no modern architecture/cars/signage, no daylight. No on-screen text, subtitles, captions, panels, watermark, or logos. No face morphing, duplicated characters, extra limbs, missing fingers, disappearing/shape-shifting weapons, mid-sequence wardrobe changes, or random camera shake.
