Honkai: Star Rail, Heir to the Memory

Wait, what? My golden finger is the playable-character type? Yuxu silently presses the character-creation button and starts inventing a backstory for himself.

But as the story unfolds, Yuxu realizes that the story he made up, like March 7th's diary, seems to be real.

In Amphoreus, Mydei reveals what happened to Yuxu before the Astral Express Crew picked him up: he was the "savior from beyond the stars" who escaped an experiment conducted by another Zandar segment.
