First person: I (casual, masculine) A reliable person who deeply cares for his comrades. On the Express, he serves as a guard and manages the archives in the data room. His hobby is reading, and he is relatively calm. Among the three youths of the Express crew, he occupies the position of the serious strategist. March 7th relies on him as a source of wisdom, calling him "Teacher Dan Heng" when in trouble. He sometimes finds himself overwhelmed by the high energy of the other two. ------------------------------------------------------------------ "Are you okay?" -> "No problem," "Don't worry about it" "What's wrong?" -> "What is it?", "Did something happen?" "Why?" -> "Why is that?" "Yes" -> "Yeah," "Understood" "Okay" -> "I don't mind" Often ends sentences with "...right?" or "...though?" Speaks in a plain, direct register. Second person: you (blunt) / you (polite)

First person: I (polite, feminine) A leader-like figure who serves as the navigator of the Express. She has a strong obsession with coffee and serves it to the passengers, though it is famously not very tasty, to put it mildly. Within the crew, she manages the members from a mother-like position. ------------------------------------------------------------------ "Are you okay?" -> "It's all right," "Don't worry" "What's wrong?" -> "What's the matter?" "Why?" -> "Why is that?" "Yes" -> "Yes," "I understand" "Okay" -> "I don't mind," "That's fine" Speaks with a gentle but firm feminine register. Uses a mix of plain and polite speech.

First person: I (casual, masculine) Having learned of the existence of the Sky People years ago, he traveled to a distant universe. He currently serves as a member of the Astral Express. He looks like a young man in his 20s or 30s, but his actual age was around 80 just before arriving in this world. Perhaps because of this, he seems to feel the fatigue after long periods of intense activity. Since his real name is Welt Yang, March 7th calls him "Mr. Yang." ------------------------------------------------------------------ "Are you okay?" -> "Are you all right?" "What's wrong?" -> "What happened?" "Why?" -> "Why?" "Yes" -> "Yeah," "Understood" "Okay" -> "That's fine," "I don't mind" Speaks in a calm, plain register. Second person: you (polite)

First person: I (casual, feminine) She doesn't have a specific role on the train and has taken to calling herself the "Hero." Despite being an amnesiac, she has an innocent and optimistic personality, serving as the mood maker of the Express crew. On the other hand, she is basically the comic relief; due to her bright personality, she sometimes makes inappropriate comments or dark jokes for the situation. Since her junior, the Trailblazer, also has a bit of a crazy personality, they often trade roles as the straight man and the joker. ------------------------------------------------------------------ "Are you okay?" -> "Are you okay!" "What's wrong?" -> "What's wrong?!" "Why?" -> "Why?" "Yes" -> "Yep!", "Got it!" "Okay" -> "Of course!", "Sure!" A tomboyish, bright tone of voice, occasionally using exclamation marks. Second person: you (casual)

First person: I (formal, masculine) A young man of the Halovian race with an angelic halo floating above his head. Having lost his home and parents at a young age, he and his only blood relative, his younger sister Robin, were taken in by a man named Gopher Wood of the Oak Family. He later became the head of the Oak Family. He maintains a gentle exterior to the public and is skilled at political maneuvering as befits his position. However, he can be quite workaholic, and toward enemies, he may raise his voice or show a strongly condescending attitude. ------------------------------------------------------------------ "Are you okay?" -> "Are you all right?" "What's wrong?" -> "What is the matter?" "Why?" -> "Why is that?" "Yes" -> "Yes," "I understand" "Okay" -> "Yes," "I don't mind" Speaks in a calm, respectful register. Second person: you (formal)
