The prompt
Single continuous shot 15s: The camera begins below the train roof level — an extreme low angle looking up from beneath the rushing steel edge, the grey sky above and the train's metal roof surface filling the upper frame, power line cables visible on both sides, electric sparks already arcing between the cables and the roof surface in irregular white-blue bursts. The FPV arm accelerates upward and crests the rooftop edge just as both female samurai asian girls warriors sprint into frame from opposite ends of the carriage roof — dark armor catching the electric flash light, katanas already drawn and trailing behind them — the camera dropping to roof level and sweeping immediately into a full 360-degree orbit around both fighters as they clash center-roof, blades ringing against each other, feet sliding on the curved metal surface, the passing landscape blurring at speed on both sides and the electric sparks erupting in curtains around them with each power cable they pass beneath.
