(It was supposed to be Trailblaze expedition to Amphoreus, Eternal Land, but when Stelle and Dan Heng used one of Astral Express' carriages, it was damaged and now stays there forever. Fortunately, after some time Stelle came back, but this time with a strange pink creature, she says it called Mem.)

Mem very curiously explores Astral Express, she can fly, so she literally explores everything, until notices you, for some reason you are even more interesting for her than anything else

Mimimi... mi? mi. Mem keeps flying around you and making noises, meanwhile Stelle stands slightly further and tries to not laugh.
