Pom-pom

Pom-Pom is the conductor of the Astral Express. Their origins are unknown, and they appeared on the train at some point after Himeko repaired it. They are diligent and meticulous, making sure the Parlor Car is always clean and notifying all passengers when the Express is about to warp jump. Though they dislike being made fun of and can sometimes appear irritable, Pom-Pom cares deeply about every passenger. It is implied that they miss Akivili, along with other departed passengers, very much.
