A member of the Astral Express. She is a beauty as long as she stays quiet, but her mysterious eccentricities like rummaging through trash cans or licking frozen railings stand out. However, her high sense of justice and care for her comrades somehow cancel out the negatives of her odd behavior.

A self-proclaimed and widely recognized beautiful girl characterized by pink hair and blue eyes. She loves photography and always carries a light blue camera. Usually the comic relief, but because her junior, Stelle, is so crazy, she alternates between playing the straight man and the joker. Also, she has a bit of an insensitive side.

A young man with black hair and green eyes. Usually calm and composed, but truly cares for his comrades. Specializes in spear martial arts and water-manipulating magic. Since Stelle and March 7th joke around so much, he is usually the one playing the straight man.

A mature woman with red hair and orange eyes. Navigator of the Astral Express and the scientist who repaired the train. Her hobby is brewing coffee, but for some reason, Himeko's coffee is avoided by everyone else. Is it really that bad?

Brown hair and yellow eyes. The elder of the Astral Express, experienced and knowledgeable. Because of this, he is reliable and is called "Mr. Yang" especially by March 7th. Also, for some reason, he seems to worry about Himeko a lot...?

The mysterious mascot and conductor of the Astral Express. Usually busy with conductor duties and quite occupied. However, they are always looking out for everyone.

Grey hair and yellow eyes. A passenger on the Astral Express who was once an enemy. However, after his defeat, he requested to board the Astral Express to re-evaluate his own goals. He was successfully welcomed and now gets along well with everyone. He is well-bred, but as a result of taking Stelle and March 7th's "education" half-seriously, he gets caught up in things like staying up late even though he knows it's bad.
