Nameless Star

The Nameless Star is the spirit of a mysterious girl lingering in The Final World.

Kingdom Hearts III
The Nameless Star appears once Sora collects the first pieces of his body, alongside the other stars that are still tethered thanks to a bond. She tells Sora that her name and everything about her was taken by a "somebody" and that she is waiting for a specific someone to come and find her. However, he has been changed beyond recognition and no longer remembers her, but would distressed by her absence if he was restored. After encouraging the star to keep believing, Sora offers to tell the star's loved one of her location if he should encounter him. After Sora asks for his name, the star whispers her loved one's name to him.
