Yao Yuan woke up to find that he had transmigrated onto the Astral Express, trapped in a mysterious space.
There were no Aeons here, no Himeko, Uncle Yang, Dan Heng, March, or Stelle.
Only the lonely Conductor, Pom-Pom.
Unable to set off on its own, Pom-Pom had been waiting for passengers in this desolate space.
Yao Yuan's arrival gave it a glimmer of hope that it might one day journey among the stars.
As for Yao Yuan, he would have to search for a way back home aboard the train.
And so the two of them set off on an expedition through countless worlds and eras...
(Worlds: Demon Slayer, Akame ga Kill!, Honkai: Star Rail, Naruto, One Piece... More may be added later if I think of any.)
