Dark realistic tokusatsu transformation on an apocalyptic battlefield. A gloomy heroine in the reference image with a torn wasteland dress stands under a gray-blue sky filled with smoke and flying demons. A matte metal ring with a golden crystal on her finger. Single continuous shot, handheld, cinematic IMAX style.
She slowly raises her hand-eyes suddenly glow white-gold, cracking with light.

She shouts: "Henshin!"

The crystal shatters-blue energy erupts. Shockwaves distort the air. Her body tears apart-red smoke, blue lightning, golden particles spreading across her flesh. Clothes burn away. Biological armor grows like iridescent scales. Metal plates collide with sparks.
A golden mask forms unevenly-compound eyes flicker to life.

Final form: flame-gold Thunder Dragon armor, glowing cracks, horned helmet, unstable energy pulsing.
She lowers into a fighting stance-draws a lightning blade from her hand. Instant burst forward-ground shatters, explosions everywhere.
