Starry Sky Railway: Kevin the Savior Forced to Work Overtime

It seems I've been transported into the world of Kevin after his liberation. I originally planned to stay quietly until the Post-Honkai Odyssey, but instead I've been thrown into the world of the Star Railway… Even after being transported, will I still have to work overtime? (Key elements of this book: Kevin + chat group, will travel to other worlds, and incidentally save the world. Kevin may not be a pirated version.)
