15 seconds, Use Image 4 as the exact opening frame. Image 5 is only a reference for the energy of the split-second flash-impact frames; do not recreate or directly include it.
 Character A is Amelia. Character A and Character B engage in a superhuman, physically impossible high-speed sword duel. Master-level sakuga, pure 2D hand-drawn animation, extreme shōnen energy, precise sword choreography, explosive acceleration, violent directional changes, aggressive foreshortening, sharp silhouettes, flowing smear frames and overwhelming speed.
 One continuous unbroken shot with no cuts or pauses. Prioritise rapid whip-pans, sudden push-ins, extreme close-ups, blades passing beside the lens and fast perspective shifts. Let the camera move freely while maintaining clear spatial continuity.
 Amelia attacks relentlessly, remains completely uninjured and controls the entire fight. She is always faster, always leading and never loses the advantage. Character B can block, evade and counter briefly, but is continuously overwhelmed. Space four extremely brief flash-impact frames throughout the full 15 seconds, each lasting only a split second and punctuating the strongest clashes without interrupting the continuous action.
 Build toward a clearly decisive final exchange in which Amelia wins. End on the final impact from a low-angle view over Amelia’s shoulder as she lands in a powerful three-point crouch with one hand planted on the floor. Character B is visibly defeated beyond her. Amelia remains composed, motionless and victorious as dust and debris rise around her.
 Keep both characters, faces, hair, clothing, anatomy, colours and weapons perfectly consistent. Exactly two characters and one sword per character. No injuries to Amelia, no broken anatomy, no duplicated limbs or weapons, no character merging, no style drift, no recolouring, no relighting, no 3D CGI, no photorealism, no text overlays and no music. Natural combat sound only: sword clashes, blade swishes, impacts, footsteps, cloth movement, debris and breathing.
