Honkai: Star Rail Stay at Space Station Hidden Ending (JP Audio)
You can actually choose to stay at the space station rather than join the express for a quick hidden ending. Pretty cool, with some intrigue making you wonder what exactly happened to them when you didn't join. It then just boots you back to the main menu after the credits and you can no longer choose this ending. To get this, just do as in the video after completing Herta's first simulation mission. Get her permission then tell Asta then tell Himeko.
