Black Clover

A red, slit-pupil eye fills the screen, then the view pulls back to reveal a dark, spiky-haired figure with glowing white hair and a red aura, standing in a dark red void. The scene cuts to a close-up of a character screaming, then to a memory of the same figure being embraced by a large, green, plant-like entity, before returning to the figure floating in the red void.
