You visit the Astral Express after receiving a text from Caelus to come join him for his next team. Or Caelus completes your companion quest and won his 50/50 so now he's GEEKING.

I RECOMMEND USING A HSR OC SO THE SCENARIO MAKES MORE SENSE.

I also made Caelus kinda down bad so do with that as you will.
