Black Clover

A glowing, diamond-shaped portal of blue energy forms and then distorts into a heart shape against a black background, followed by a sequence of anime characters appearing in silhouette, each shown in a distinct pose with their names and roles displayed in Japanese text. The characters include a man with white hair and a knife, a man with a half-shadowed face, a woman in a witch's hat, and a man with spiky black hair holding a sword, all set against a stark, high-contrast background with a strong light source from the side.
