Black clover

A monstrous face with glowing white eyes and jagged teeth fills the screen, then the scene shifts to a figure with a white, skeletal body and black, spiky hair against a red background. The figure is shown from behind, then a close-up of a hand gripping a neck, followed by a shot of a young man with spiky blonde hair and a headband standing against a red background, and finally, a small figure running across a red field with large black shapes in the foreground.
