Brilliant Progress in the World of Detective Conan

An accident leaves the Astral Express crew stranded on an unexplored planet. Good news: There are other people stranded there, just like them, and plenty of records of their experiences. Bad news: Time on this planet has serious problems. It keeps resetting, and people are getting murdered all the time. What a dangerous planet. To find a way off, the Astral Express crew try all sorts of things. Gin, stranded here as a Xianzhou native: Hey, aren't you the dangerous ones? It wasn't this ridiculous when I first got here!! The first time he saw March 7th save a police officer with a single shield, then send a bomber flying, Gin didn't know what to say. The second time he saw Dan Heng do a good deed alongside the organization's undercover agent, Gin knew what to say, but couldn't say it. The third time he saw the two members of the Astral Express act out a ○-shin-style betrayal between kin in front of the good guys, Gin could already make deadpan remarks about it. Stelle: Gin-chan, you know every good story needs someone to make sarcastic comments. Sorry, but that's you. On countless nights, Gin would suddenly remember the first day they met. If time really could reset to that day, Gin would choose to run on the spot. At some point, the world began to grow absurd. Time repeating itself, the dead coming back to life. A train has come because of this. Please note: 1. Gin will be redeemed, and the Astral Express crew will turn evil. Don't read if you dislike that. 2. Apologies for out-of-character moments. 3. Both Stelle and Caelus are in it. I couldn't choose whether to write Stelle or Caelus, so I included them both. 4. I'll save the characters who can be saved. Isn't that one of the fun parts of writing fanfiction? 5. I'm happy to hear suggestions, but please be kind to each other. Theme: May this journey lead us to the stars
