Terror in Resonance

A close-up of an anime character's eye fills the screen, then the scene cuts to a swimming pool with figures on the deck, followed by a medium shot of a young man with dark hair, then a close-up of a smartphone displaying a list of messages, then a side profile of a young man with dark hair, and finally a close-up of a young woman with dark hair looking distressed. The sequence takes place in various indoor settings, including a dimly lit room, a pool area, and a location with an escalator.
