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 someone, and that she is waiting for another specific person to come and find her. However, the person she is waiting for has been transformed and no longer remembers her, even though he would miss her if he could. Sora offers to help reconnect the pair, and the star whispers her loved one's name to him.
