The city has been destroyed.

A young woman in a school uniform stands on a bridge at dusk, looking down with a somber expression, then the scene cuts to a close-up of her face as she looks up with a determined gaze. The sequence continues with a different girl with brown pigtails looking surprised, followed by a girl with glasses and a clear umbrella standing in the rain at night, then walking across a wet street at a railroad crossing, and finally a girl with blonde hair looking down, followed by a close-up of a girl with pink hair and a red top looking down with a sad expression.
