Kill Furrys

A man in a plague doctor mask stands atop a stone ruin in a forest, then the scene cuts to a close-up of the mask, followed by a character with a yellow cone head and a dark-haired figure with glowing red eyes. The sequence continues with the cone-headed character standing in a ruined archway, then the dark-haired figure holding a club, and finally the two characters fighting in the debris-strewn area, ending with the dark-haired figure lying on the ground.
