Tokyo Ghoul

A pair of hands holds a spiral-bound notebook, then opens it to reveal a photograph of an anime girl with purple hair and red eyes standing on a city rooftop at night; the image in the notebook rapidly distorts into a chaotic, colorful explosion before transitioning to a close-up of the girl's face, then a full-body shot of her in a dark, industrial setting, and finally a side profile of her with a red, winged creature perched on her shoulder.
