I'm Undead.

A stylized female warrior with a red cape and spear battles a large, shadowy monster in a snowy landscape, the monster falling as red particles explode around it. The scene shifts to a close-up of a monstrous creature with sharp limbs, then to a man and a woman in a warm, golden-lit setting, followed by a dark scene where a character in white fights a large, shadowy creature with a red crescent blade.
