Tokyo Ghoul

A character with black hair and a red scarf appears in a close-up, followed by a character with purple hair looking forward, then a dark scene with glowing particles, a close-up of a character with black hair and a character with purple hair, a character with black hair laughing, and finally a dark figure facing a swirling red and black vortex. The sequence takes place against a white background with brief transitions to dark, abstract scenes.
