Black Clover

A red, slit-pupil eye fills the screen, then the scene cuts to a dark figure with spiky white hair and glowing red eyes standing in a field under a stormy sky, facing a character with silver hair. The silver-haired character screams in terror as the white-haired figure, now revealed to have a monstrous, skeletal face, embraces them from behind. The sequence ends with the white-haired figure lying motionless on a red surface, their face illuminated by a red glow.
