Prologue - Gathering the Cast

The people from Honkai Impact are suddenly teleported to a theatre where they will watch their world as they follow the life of a transmigrator who has a tough life but unlimited kindness. This story will also bring back some characters from the dead so read to find out.
-------------------
This is an original Honkai Impact fanfiction with reaction in the mix. The characters will react to my original story. But I will say here that I don't play the game and the minimum knowledge I have is from Honkai fanfictions I have read before so the timeline and the things might not be consistent but you could help by telling me about the key events in the comments.
