Past-Tense: Her Spirit's Presence

Kosmo wakes up in a field, not sure where she is. But here's the thing-she doesn't remember anything about herself. She can only recall her name-Kosmo. With nothing but a diamond necklace and the skin on her body, she decides that she wants to learn about her past... who she is. She can't be herself without knowing who she was.

But here's another thing-she's a ghost. And when she finally finds shelter to stay at, the Elf Village, there's a girl who looks almost identical to Kosmo herself. Were they family? She didn't know, but somehow, she knew that this girl was connected to her past.
