subject_definitions: <Picture 1> is the magic-girl officer cadet (character reference, keep her 2D anime style). <Picture 2> is the wooden frame structure (target reference).
summary: She casts an explosive pale-blue magic orb at the wooden structure.
[0s-0.5s] Face close-up: confident smile, eyes sharp, a brief beat.
[0.5s-2.5s] Camera facing her, telephoto: her face holds in close-up as a pale-blue circular magic circle flares open around the staff tip; then, without a cut, the camera eases backward at a barely-there pace while the circle's rings ignite one by one, energy spilling past the rim — the circle swelling relentlessly until it fills the entire frame and pushes beyond the screen edges, her face sinking toward the bottom edge, the magic looming over everything.
[2.5s-3s] Hard cut to behind her: camera fixed over her shoulder, facing <Picture 2>, the wooden structure in frame; in the same instant she thrusts the staff and the pale-blue orb blasts off with a blazing trail.
[3s-4.5s] Fixed over-the-shoulder shot: the orb detonates on the wooden frame — pale-blue flash, shockwave, beams snap, debris and splinters burst outward, the frame shudders with the impact.
[4.5s-6.5s] Aftermath: broken timber falls, fading blue sparks and dust drift; she lowers her staff and settles, calm, seen from behind; the camera holds.
Camera: telephoto face close-up, then an almost imperceptible slow backward retreat as the magic circle swells to fill and overflow the frame; one hard cut to a fixed over-the-shoulder shot; no further cuts, handheld tremor on impact only.
Audio: crisp magical chime swelling as the rings ignite, sharp launch whoosh at the cut, explosive boom and splintering on impact, soft wind after; light fantasy BGM. No dialogue.
