Black clover

A close-up of a character's eye with a glowing green slit pupil, followed by a red-tinted silhouette of a monstrous figure with horns and wings, then a shot of a body lying on the ground, a character with a red mark on their face, a dark figure with glowing red eyes, and finally a black silhouette of a winged creature against a red background. The sequence depicts a transformation or summoning of a demonic entity, with the character's eye reflecting intense focus or possession, set against a dark, ominous environment.
