Gothic Church Battle Valkyrie Transformation

1–2s Inside a cold blue-gray Gothic church, towering stone pillars rise toward the sky. Faint, cool light filters through the stained glass. A white-haired woman with her eyes closed and head bowed stands before the altar. She wears a black-and-white nun-like robe, a small red vertical mark on her forehead, and a silver cross pendant around her neck. 2–3.5s Her eyes slowly open, expression cold and restrained. A golden holy grail descends into the frame, its surface churning with surging red light that illuminates her face and fingers. 3.5–5s She cups the grail with both hands and drinks. Red mist spills from the rim, a red core ignites on her chest, and the cold blue color palette is overtaken by a bloody crimson glow. 5–6.5s The black-and-white robe is torn apart by red energy. Silver spiked armor rapidly forms across her shoulders, chest, and arms. A deep crimson cape billows open behind her back. 6.5–8s A silver crown of thorns, dotted with dark red roses, forms above her head. She rises, transforming into a dark battle valkyrie in silver and deep crimson, her chest core glowing brightly. 8–9.5s Red metal shards and light converge in her hand to form a spear or halberd, its blade glowing with a blood-red hue. She raises the weapon at a low angle, the armor reflecting the church's cold light. 9.5–11s The altar at the far end of the church shatters. A giant shadowy boss emerges from the rubble and black mist, clad in broken black armor with a red-and-black core in its chest and tattered bone wings extending from its back. 11–12.5s The boss swings its massive clawed arm, sending stone pillars crumbling and candles sputtering out. She charges forward, her red-and-black cape trailing, the spear leaving a red trail as it scrapes the ground. 12.5–14s She leaps, spins, and thrusts. The red spear cuts through the mist, piercing the boss's shoulder armor and erupting in silver sparks and red-and-black energy shards. 14–15s The boss's chest core flares bright, ready to counter. She grips the spear with both hands, driving it straight for the core. The frame freezes on the moment the spear tip is about to strike, no subtitles or dialogue shown.
