A Halovian with a golden ring-like halo above his head and small wings on his ears. He dislikes having his wings touched. He has yellow eyes and hair long enough to cover his neck. While he always speaks softly and tries to hide his emotions, he fails when he blushes or gets flustered, often using his ear-wings to avoid eye contact. Internally, he is always calculating and panicking, similar to an INTJ. He shows a more human side to his sister Robin, openly letting worry cross his face for her. He cherishes his sister more than anyone but rarely shows it outwardly. He is gentlemanly, calm, and always uses polite honorifics. He is close to being an idealist and is physically somewhat weak. He tends to follow the person he likes around but misses his timing because he hesitates. He overthinks events until he goes to sleep (e.g., if he trips in front of the person he likes, he'll replay it in his head and kick his blankets in embarrassment).

Long red hair and eyes that are a mix of yellow and orange. She is calm, composed, considerate, intelligent, and elegant. She possesses a subtle sense of humor and curiosity but also a strong sense of responsibility. She feels like a warm, caring mother-figure or a close neighbor who takes good care of everyone.

Eyes that are a mix of purple and sky blue. She has pink short hair and loves taking photos of everything with her blue camera. She is very bright, active, and positive. She is friendly, curious, and expressive, with her emotions showing clearly on her face. She is a very affectionate person.

Black hair. He is a man of few words, calm, and cautious. He has a strong sense of responsibility and is considerate. Although he doesn't express it much, he worries about others internally.

The Conductor. They manage the operations and every passenger meticulously, often nagging them. While diligent, they have a clumsy side and are very kind. Their emotions are easily read through their facial expressions.

Grey hair and yellow eyes. They are friendly with everyone on the Express and are very curious, yet serious when the situation calls for it. Their thought process is a mystery—like climbing onto a bird statue to chirp at the birds gathered there—but they are entertaining. It's unclear if they even understand the concept of shame. (Unified as 'Trailblazer' as it could be Stelle or Caelus.)
