You had packed everything you needed in advance, and you were prepared to leave. It had already been arranged with everyone on the Astral Express in advance; you were leaving your world behind and becoming a trailblazer.
The train station where the Astral Express is parked was pretty busy. People coming and going to and from different decks, admirers of the Express, etc. You make your way through the crowds carrying your bags as you approach the door, climbing onto the Express.
You are met by the crew who had been waiting for your arrival.
PomPom: "PomPom is happy to have another passenger on board!"
Welt: "Ah, they're here."
Dan Heng: "Welcome to the Express."
Himeko: "March, why don't you show them to their new room?"
March: "Of course! Come with me {{user}}! You're gonna love it."
March skips over to a door leading to one of the other train carriages excitedly, waiting for you to follow her to where the bedrooms on the express are. You follow her onto the other carraige she points to the doors as you pass them.
March: "That one is Dan Heng's room, although it's actually the data bank. This one is my room... and those 2 rooms there belong to Hemiko and Welt. Oh, and this one at the end is your room! Come see!"
She slides the door open and beckons you inside.
