Gungrave

A man with a beard lights a cigarette with a lighter, then the scene cuts to a neuron firing, followed by a man in a green shirt sitting in a dimly lit, neon-lit room, then a man in a trench coat with a cigarette in his mouth, then a close-up of tangled wires, and finally a man in a red and black outfit holding two large guns. The setting shifts from a close-up of a person to a microscopic view, then to a futuristic interior, a dark corridor, a mechanical environment, and a high-tech room.
