Reborn

A character descends through blue water toward a coral reef, followed by a sequence of anime characters: two girls standing together as petals fall, a girl with dark hair and a hat looking sideways, a girl with brown hair and a hat smiling as yellow leaves swirl around her, a close-up of a girl with dark hair and blue eyes looking down, and finally a close-up of a girl with orange hair smiling as white petals fall.
