Pom-Pom

帕姆 / パム

Pom-Pom serves as the conductor of the Astral Express. Their origins remain unknown, and they appeared on the train at some point after Himeko repaired it. Diligent and meticulous, Pom-Pom ensures the Parlor Car is always clean and notifies all passengers when the Express is about to warp jump. Although 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.
Pom-Pom appears to be a small, rabbit-like creature with large ears. They have dark gray and white fur, blue eyes, and wear a modified hog-head hat and a large-collared coat that conceals their arms from view. Their attire consists mainly of red and black colors, with gold embellishments and some resembling gears. They carry a white satchel with gold buckles on their right side, and have a red, white, and gold band wrapped around their left ear.
As seen in the Travel Log images, they use their ears as if they were hands to hold books.
