30 秒手绘动漫短片，怎么做出来的？

Use @[char1 ref] for Erza's appearance and two swords; use @[char2 ref] for Saito's appearance and single katana. Both supply the painterly anime style, not poses. Animate new full-body silhouettes rather than sliding or rotating the reference crouches.

30 seconds, six shots. Saito repeatedly escapes under Erza's left arm to attack from behind. After his counter sends her tumbling, she uses that habit as bait and closes the exit with her second blade. Show this reversal through their changed routes.

Fast real-time sakuga combat: explosive travel, full torso and hip turns, extended limbs, deep foreshortening and directional smears resolving into clear anatomy at contact. Carry parries into displacement and recoveries into attacks. No slow motion, hit-stop, suspended staring, prolonged blade locks or repeated crouching silhouettes. Both fight while travelling through the sky; contacts, kicks and body rotation redirect their trajectories.

Exactly three swords: Erza holds one separate katana in each hand; Saito holds one in his right hand, his left hand empty for balance. Hilts stay in their owning hands. Erza's blades work independently, one engaging his weapon while the other threatens an opening. No dropped, merged, duplicated or floating weapons.

Shot 1, 0-4s. Wide diagonal chase, camera rushing alongside the bodies. Erza dives from upper left in a stretched silhouette, cutting down with her right blade while opening the left for a follow-up. Saito rises from lower right, deflects the first blade and rolls sideways beneath her left arm. He shoots out behind her left shoulder as she overshoots. Show the passage and changed positions together; both immediately twist back toward the fight.

Shot 2, 4-10s. Fast lateral tracking through a horizontal pursuit. Erza chases with alternating cuts, her hips turning each missed swing into the next. Saito arches backward beneath a sweep, stretches sideways through the opening and answers with a rising slash. Erza cartwheels her body over that counter and attacks out of the inversion. Saito again slips under her left arm and emerges behind her left shoulder, forcing her to reverse while he is already attacking. Long extended silhouettes snap into sharp folds.

Shot 3, 10-14s. Side-on full-body view preserving the escape direction. From behind her left shoulder, Saito slices the edge of Erza's left sleeve and drives a side kick into her upper arm. The kick throws her forward into an uncontrolled end-over-end tumble; he recoils into pursuit. Track her fall as she turns her head to keep him in view and pulls both swords close to recover. Her torn sleeve persists as the tumble carries directly into recovery.

Shot 4, 14-20s. Drop with Erza's tumble, following her turn back into Saito's approach. She repeats the right-hand descending attack and exposes the same space beneath her left arm, but keeps the left blade drawn back. Saito takes the familiar low route. Erza rotates her torso toward his destination and snaps the delayed left blade across his exit. He must parry immediately and corkscrew sideways out of the lane, legs flung overhead by his evasive rotation. Keep both bodies visible: she takes the route and forces him away, blades touching and separating instantly.

Shot 5, 20-25s. Rise with Saito's corkscrew as he changes tactics, extending out of it into an overhead descending slash. Erza rolls side-on beneath the attack, redirects his katana with her right sword and sweeps her separate left blade across his return path. He twists clear and answers on the way past; she ducks through the return without stopping. Glancing contact sends them apart on opposing arcs. Both convert separation straight into converging attacks across the cut.

Shot 6, 25-30s. Reprise the opening's wide diagonal geometry at greater speed. Saito commits to his crossing cut; Erza turns it aside with her right sword, then closes his familiar low escape with the delayed left. A violent crossing contact snaps directly into follow-through. Erza drives through the centre while Saito is forced to corkscrew off to the side. Pull wide with their separating bodies so the changed outcome reads before the effect: two thin brushlike slash trails cross through displaced cloud haze, briefly making the sky seem torn. End with both still travelling, hair and torn hems whipping.

Pale blue-gray sky, diffuse daylight, soft clouds, elastic sketch contours and compact hand-painted shading. Sparse thin arcs, silhouette smears and tiny flecks sourced from motion or contact. No energy beams or portals. Rapid air cuts, cloth snaps, dry steel cracks and a blunt kick impact; short sound tails keep the next attack audible. No dialogue, subtitles, on-screen text or music.
