Fourth of July

A white-haired character in a long coat holds a sword in a futuristic, blue-lit room, then the scene cuts to a close-up of their face before shifting to a dark-haired character in a coat and scarf who generates a glowing blue energy sphere in their hand, followed by a shot of a mechanical arm moving, and finally the dark-haired character extends their hand, releasing a burst of blue energy that forms into a swirling, crackling arc.
