Cursed Swordsman — 10s MOBA Ability Showcase | Jujutsu Kaisen AI Video
Final Video: Cursed Swordsman — A 10-Second MOBA Ability Showcase
Cursed Swordsman is a ten-second champion-ability spotlight told in the language of a MOBA hero reveal: one swordsman, one guardian, one escalating kit. It opens on a ring glint and a blade crawling with violet cursed energy, then moves through a shadow slash, a guardian sweep, a mirror dash and a full Rika manifestation that fills the frame with a moonlit skull and two heavy arms.
No narrator, no HUD clutter, no montage of unrelated shots — just one continuous power curve from passive to ultimate, staged on a cracked battlefield under a cold full moon. The swordsman is Yuta Okkotsu; the guardian is Rika, kept in her canon skull-and-black-mass form rather than a dragon or a winged demon.

The Video
10 seconds · 16:9 · 1280 × 720 · single image-to-video pass · no dialogue — rendered with Seedance 2.0 Fast from one 16:9 reference still. The timeline is authored entirely in the prompt: PASSIVE (0–1.5s), Q cursed slash (1.5–3.5s), W guardian summon (3.5–5.5s), E mirror dash (5.5–7.5s), R full manifestation (7.5–10s).
How It Was Made
Production Process Breakdown
The build starts from the canon relationship, not a generic swordsman. Yuta Okkotsu is locked as a tired teenage special-grade sorcerer: black medium messy hair, dark eyes, faint under-eye shadows, a simple white high-collar uniform, a real steel katana, and the ring on his gripping hand. Rika is locked just as tightly: a pale eyeless skull head with horizontal structural lines, long teeth, a massive black cursed-energy body, two thick muscular human-like arms and black fingernails. The negative list is part of the design — no dragon, no wings, no glowing eye pair, no energy-blade katana.
A single 16:9 still establishes the whole look: painterly commercial MOBA splash, cold blue-violet moonlight, deep navy shadows, violet-black curse ribbons, cracked stone ground and a full moon. The composition runs a deliberate focal path from Yuta’s tired eyes to the ring and katana grip, along the steel blade, and up to Rika’s skull. That still becomes the identity anchor for every motion pass.
The first motion test was a five-second seamless idle loop on Kling Image-to-Video: breathing, hair sway, a ring glint, smoke curling in loops and Rika’s shoulders shifting in parallax. It proved the character could move without drifting, but an idle loop is not an ability showcase — so it stayed as a skin-idle test rather than the deliverable.
The final showcase was rendered in one ten-second Seedance 2.0 Fast image-to-video pass. The prompt writes the kit as five escalating beats and holds the camera in a smooth action-game spotlight: a close passive beat, a diagonal Q slash, a W guardian sweep, an E mirror-dash combo, and an R that erupts into a full Rika manifestation. Every beat carries the same identity constraints, so the face, uniform, katana, ring and guardian silhouette survive the cuts.
Two further ten-second passes explored a different register: top-down isometric “real match” footage on a Summoner’s-Rift-style lane, complete with QWER cooldowns, health bars, floating damage numbers and a minimap. Both were kept as alternate cuts — useful references for how the same kit reads as gameplay rather than key art.
Generation Prompt
The full prompt behind the final ten-second render. One 16:9 reference still is passed in as the source image; the ability beats, camera behavior, VFX rules and hard negative constraints are all authored here.
Create a 10-second new champion ability-showcase trailer in the style of a League of Legends / Honor of Kings hero spotlight, starting from the source image: a young black-haired cursed swordsman in a white high-collar uniform, real steel katana, ring on his gripping hand, with a huge eyeless white-skull-headed black smoky guardian spirit behind him. Keep his identity, face, uniform, katana, ring, and the skull-headed guardian's silhouette consistent across all shots. In-game cinematic MOBA presentation, third-person action camera, ability name beats, clean game-trailer pacing, cold moonlit blue-violet supernatural palette, painterly fantasy splash finish.
Show the kit as escalating ability beats:
0-1.5s PASSIVE: close shot, the swordsman's katana edge ignites with crawling violet cursed energy and the ring glints; faint skull guardian breathes behind him.
1.5-3.5s Q - cursed slash: he dashes diagonally and performs a fast katana slash that leaves a violet-black crescent energy arc cutting through cursed debris.
3.5-5.5s W - guardian summon: the eyeless skull-headed black guardian partially manifests, sweeping its thick human-like arm forward as a defensive-aggressive zone of black cursed mass and smoky tendrils.
5.5-7.5s E - copy / mirror dash: the swordsman blinks with a violet afterimage trail and unleashes a layered combo of mirrored cursed slashes, energy ribbons spiraling.
7.5-10s R - ultimate full manifestation: the guardian fully erupts behind him into a towering skull-and-black-mass spirit, long teeth and two muscular arms framing a massive moonlit cursed-energy detonation as the swordsman raises his katana; end on a cinematic hero pose with an ultimate-cast camera push.
Camera: dynamic action-game spotlight, smooth pushes and orbits, slight slow-motion on the ultimate, no shaky handheld. Keep VFX readable: violet-black cursed energy, white skull highlights, moon rim light, smoky tendrils, energy ribbons, ground cracks. The katana stays solid steel, not a glowing energy sword. The guardian stays a skull-headed black cursed spirit, never a dragon, never winged, no glowing eye pair.
Avoid: real-world logos, watermark, on-screen UI copyright marks, garbled text, face deformation, age change, extra fingers, warped katana, missing ring, guardian turning into a dragon or winged beast, glowing eyes on the guardian, new unrelated characters, scene becoming a different setting, jarring cuts that break identity continuity.
Asset Prompts
<p>@Yuta Okkotsu, Create a faithful original League-of-Legends-style champion splash illustration, wide 16:9, of Yuta Okkotsu unleashing Rika full manifestation. Use the Yuta reference only for identity anchors: black medium messy hair, teenage face, dark eyes, white high-collar uniform impression, and restrained haunted mood. Do not copy the exact official pose, exact framing, linework, costume folds, background, or screenshot composition.</p><p>LOCKED YUTA: teenage special grade sorcerer, black medium-length messy hair, dark blue eyes, gentle haunted face with subtle under-eye shadows, restrained anxiety becoming quiet resolve, simple white high-collar Tokyo Jujutsu High uniform with front buttons, real steel katana. He must feel like a tired teenage sorcerer carrying guilt and enormous power, not a mature prince, idol, or adult fantasy swordsman.</p><p>LOCKED RIKA: Queen of Curses, not a dragon. Rika has a white skull-shaped head with horizontal structural lines, no visible eyes, long teeth, massive black cursed-energy body, two thick muscular human-like arms, black fingernails. Her body is black cursed mass and vengeful spirit matter with a pale skull head emerging from it. She is protective, terrifying, grotesque, mournful. Absolutely avoid dragon, ice beast, winged demon, fantasy guardian, serpent, wyvern, lizard, glowing eye pair, wings, dragon snout, or horns that read as dragon.</p><p>COMPOSITION: high-end MOBA champion splash, moonlit battlefield, cinematic diagonal composition. Yuta stands left-center/front in low three-quarter stance, katana diagonal. One visible hand grips the katana; Yuta's ring is subtly readable near the grip as the Rika bond trigger. Rika looms behind and above as huge pale-skull-and-black-mass cursed spirit, two muscular human-like arms framing the scene. Focal path: Yuta tired eyes -> ring and katana grip -> real steel blade with crawling cursed energy -> Rika eyeless skull head and long teeth.</p><p>LIGHTING/MATERIALS: cold blue-white moon rim light, violet-black cursed energy, deep navy shadows, matte white uniform, clumped black hair, real steel katana, small metallic ring highlight, rough bone skull texture, black curse-mass body, black fingernails, smoky tendrils. Katana remains steel, not a lightsaber.</p><p>HANDS: one visible gripping hand only, natural fingers around handle, thumb correct, exactly five fingers if visible, ring visible without distortion; other hand hidden by sleeve/energy.</p><p>STYLE: commercial fantasy MOBA champion splash, thick painterly brushwork, large value grouping, hard-soft edge rhythm, selective focal detail. No text, no logo, no watermark, no official screenshot composition, no dragon Rika, no glowing eye pair on Rika, no mature idol face, no plastic CGI, no deformed hands.</p>
<p>Animate the source image as a seamless 5-second looping premium game skin idle animation, like layered 2D skeletal character animation. Preserve the source image exactly: the young black-haired swordsman, tired expression, white high-collar uniform, ring on the gripping hand, katana grip, solid steel katana, large eyeless skull-headed shadow guardian behind him, black smoky body, thick human-like arms, black fingernails, moonlit battlefield composition. Do not alter faces, pose, clothing, weapon, ring, guardian silhouette, or camera framing.</p><p>Motion should be subtle, premium, and loopable: the swordsman has a tiny breathing rise and return; hair tips and uniform edges sway softly; the ring catches a small cold glint; the steel katana reflects a slow violet-blue shimmer while staying solid metal; dark violet energy crawls along the blade and returns to starting intensity; smoke tendrils curl in circular loops; tiny particles drift and reset naturally. The skull-headed guardian slowly breathes with faint shoulder and arm parallax, the eyeless skull dips almost imperceptibly then returns, teeth catch cold moon highlights, black fingernails glint, and the black smoky mass pulses outward then back.</p><p>Camera mostly locked with only a very slight 2.5D parallax push and return so the first and last frames feel matched for a clean loop. Mood and lighting: cold moonlit blue-violet supernatural aura, deep navy shadows, controlled bloom, painterly fantasy splash finish. Avoid face deformation, age change, extra fingers, warped grip, missing ring, weapon turning into a glowing energy sword, guardian gaining glowing eyes, guardian turning into a dragon or winged beast, new characters, text, logos, scene change, heavy camera motion, sudden zooms, flicker, or non-looping explosion.</p>
<p>Create a 10-second clip that looks like REAL in-game MOBA gameplay footage on a classic Summoner's Rift-style lane map, like an actual match recording, NOT a cinematic trailer. Top-down isometric ARTS camera at about 45 degrees, the playable champion shown as a mid-scale gameplay unit on the map, gameplay camera that follows the hero.</p><p>MAP (Summoner's Rift vibe): a stylized fantasy MOBA lane with green grass terrain, stone lane path, brush/bushes, a blue-tinted river with a crossing, lane turret in the background, glowing objective markers, lane minions fighting, and a few ENEMY CHAMPION units clearly positioned down the lane. Cool natural daylight-to-dusk rift palette mixed with the champion's cold blue-violet cursed energy.</p><p>CHAMPION: the same young black-haired cursed swordsman in a white high-collar uniform with a steel katana and a ring as the source image, rendered as an in-game 3D action hero seen from the gameplay camera (not a portrait). Keep design consistent.</p><p>GAMEPLAY HUD vibe: bottom ability bar with QWER icons and cooldown sweeps, summoner spell slots, health and mana bars over units, floating yellow/white damage numbers, crit numbers, a minimap in the corner, gold/CS counter feel, ground-targeted ability range indicators. Keep all UI generic, no real-world logos, no readable copyrighted text.</p><p>ACTION TIMELINE:<br />0-2s: champion walks up the grassy lane, auto-attacks a minion wave with quick violet cursed katana slashes, small floating damage numbers.<br />2-4s: casts Q (skillshot) - a directional range indicator flashes toward the enemy champions, a flashy violet-black crescent slash with energy ribbons and after-image trails flies down the lane and hits an enemy champion, its health bar drops, hit-spark VFX.<br />4-6.5s: presses R ULTIMATE aimed directly AT the enemy champions - a large circular/cone ground indicator locks onto the enemy hero position, then a huge eyeless white-skull-headed black cursed guardian spirit erupts and lunges FORWARD toward the enemy champions, two muscular arms slamming down on top of them with a big AoE; enemy champions are caught, knocked, and take large floating damage numbers.<br />6.5-10s: the ultimate detonates on the enemy heroes with elaborate layered VFX - violet-black cursed shockwave rings, swirling smoky tendrils, white skull energy bloom, ground cracks glowing, screen-impact flash; enemy champion health bars drain to zero with KILL / double-kill notification popups, camera stays in the same top-down gameplay perspective.</p><p>Style: high-end modern League-of-Legends-style in-game graphics, clean readable Summoner's Rift gameplay rendering, extra-flashy but readable spell VFX, satisfying ability impact, top-down action. Looks like recorded ranked gameplay with HUD, not a hand-drawn splash, not a third-person movie cutscene.</p><p>Avoid: real-world brand or game logos, watermark, readable copyrighted text or garbled text, first-person view, pure cinematic close-up portrait framing, the guardian turning into a dragon or winged beast, glowing eye pair on the guardian, katana becoming a glowing energy sword, identity drift, extra fingers, the ultimate firing into empty space instead of at the enemy champions.</p>
