Honkai Star Rail x Oc reader

For as long she could remember, Aira has always been on the Astral Express. She has little memory of her past, but has no idea about where she came from. Himeko and Mr. Welt Yang took her in when she was a child. Based from what they know, Aira was abducted from her homeworld from an early age, hence why she has little memory about where she came from.

In the beginning, she was so scared, but over time, she slowly opened up to Miss Himeko and Mr. Welt Yang even the train conductor Pom Pom. As she journeys through the galaxy, she met Dan Heng and March 7th, just like with Miss Himeko and Mr. Welt Yang, it took her a long while to open up to them and later on became friends

What kind of adventures await for the young trailblazer including her friends? Will she find the answers about her past and why she taken away from an early age?
