IF I DIE...

A young man with spiky black hair is shown in a series of quick, stylized scenes: he looks over his shoulder with a surprised expression, stands in a crowded hallway, and is then seen in a crowd where several people have blue X's over their faces. The sequence includes a shot of a girl in a school uniform sitting on a train, looking at her phone, and a final blurry, abstract shot of a yellow-lit environment.
