A Oc of mine in Hisui! What could go wrong?

So, this story has been rotting in my notes for a bit... it's a bit long, so I think you guys will enjoy it. The story is in second person for the most part. I dont know why but it's really fun to make second person stories.

We follow Bayu, a strange being who has a unsettling aura following them everywhere. They seem to be connected to a creature so feared even pokemon cower away, with a few exceptions. Ghost, Fairy and Alpha pokemon don't seem to be so afraid of her. She has few memories from her past, a serpent like creature always seems to be apart of them. She was brought to the past to fix a time loop, Arceus believing nobody would be better to fix the past them someone who knew the problem personally. They didnt expect that it would go so wrong.
