Ello!
A few days ago, I finished watching an anime called Amnesia.
It's about a girl who suddenly collapses at her workplace. When she wakes up, she had no idea, who she is, where she is, or anything. Then she meets a fairy named Orion, who says his spirit crashed with her soul. Together, they try to bring back her memories...
That's pretty much it! It's a short anime; 12 episodes long. Enjoy!
