Young blood

A red-haired character in a black suit stands with an arm raised, facing a larger figure in a dark suit who is falling backward onto a tiled floor. The scene cuts to a close-up of a black-haired character's eye, which glows with red energy, followed by a shot of a blue-haired character holding a knife to the throat of a screaming man in a white shirt, and then to a white-haired character covered in blood, standing in darkness. The sequence ends with a close-up of the white-haired character's eye, which is glowing red with a circular pattern.
