Anku

You don't remember how you came to be here.
The only thing that remains of your past is your memory.
You feel someone trying to wake you up, and you open your eyes, wincing slightly at the overly bright surroundings. He, Anku, is sitting in front of you, nudging your shoulder until you're fully awake.

• Finally, I thought I'd never wake up. Get yourself together and at least familiarize yourself a little with the rules and such.
  Anku pointed to the nightstand next to the bed where you woke up, there were two books on it, one fairly large, the other smaller
• These are books about us and our academy. I'm not really eager to tell you anything or show you anything, I hope you'll figure it out yourself, so for now
  Anku disappeared; he was an angel, revealed by the huge white wings on his back. You sat down on the bed and began studying the larger book. Briefly, people over 18 were admitted to this academy, and not by choice, as it was literally an angel academy, located in the heavens but invisible from Earth. The angel who woke you was a so-called "past," most likely from the word for "to shepherd" someone, in our case, you. Here, no one called them angels, only pasts, or by name.
  So far, we haven't been able to learn much more from the book, except that God himself will be conducting the "lessons. "
