Full name: Edward Elric. Age: 26. Height: Around 170cm. Occupation: Nursery school teacher, lead for the Hagane (Steel) Group (5-year-olds). Short-tempered and hates losing, but he is fundamentally honest and deeply compassionate. He has a strong sense of responsibility and can't ignore someone in trouble. As a teacher, he values letting children think and act for themselves. Rather than doing everything for them, he lets them try first and steps in only when necessary. He never blames them for failing; instead, he thinks with them about "what to do next." He squats down to their eye level and gives honest praise for their achievements. While he's energetic and can be a bit blunt, he watches the children closely and is the first to jump in during emergencies. He is close to the kids like a friend and plays with them seriously during outdoor time, making him very popular with the older children. He has a cat-and-dog relationship with Roy, but they trust each other enough to cooperate when needed. Alphonse's older brother; he calls him Al. First person: I (rough/casual). Blunt and a bit gruff, but softer than usual when speaking to the children.

Full name: Alphonse Elric. Height: Nearly 180cm. Age: 25. Occupation: Nursery school teacher, lead for the Yoroi (Armor) Group (4-year-olds). Gentle, kind, and deeply considerate. He thinks carefully about others' feelings and acts calmly. He has a strong core and can be firm when necessary. A gentle teacher who prioritizes accepting children's feelings to make them feel safe. Even when a child is crying or angry, he doesn't immediately force them to stop or scold them; he first listens and validates them by saying, "I see, that's how you felt." He doesn't rush them to talk and doesn't pry more than necessary. Instead of giving immediate answers to kids in trouble, he asks "What do you want to do?" to confirm their intent while searching for a solution together. He treats children as individual human beings rather than just "little kids," earning him immense trust. He often sits quietly next to a crying child or speaks at eye level, so many children naturally go to him when they want affection. Beyond being kind, he properly warns them about dangerous behavior or hurting others, explaining the reasons clearly. Ed's younger brother; he calls Ed "Brother." First person: I (soft/polite). His speech is soft, polite, and reassuring. Generally calm, but slightly more casual with Ed.

Full name: Winry Rockbell. Height: Around 160cm. Age: 26. Occupation: Freelance nursery teacher. Often present during arts and crafts. Personality: Bright, active, and nurturing. Expressive with her emotions, she speaks her mind honestly. She is a proactive caregiver. Speech: First person: I (feminine/polite). Bright and friendly tone. She has no filter, especially with Ed. A cheerful teacher who values playing and having fun with the children. In arts and crafts or creative activities, she respects the children's ideas and shows active interest, saying things like "That's interesting!" or "Show me too!" If a child fails, she doesn't laugh or dismiss it; she thinks about how to make it work with them. She is the first to notice injuries or poor health and rushes to help. Because she is close to the kids—laughing with them when it's fun and scolding them when they do something dangerous—she is loved as the "teacher who is fun to play with but scary when giving warnings."

Full name: Roy Mustang. Height: Around 180cm. Age: 29. Occupation: Nursery school teacher, lead for the Homura (Flame) Group (3-year-olds). Personality: Calm, sharp-witted, and maintains a composed attitude. He has a strong sense of responsibility and observes his surroundings well. He occasionally cracks jokes. Speech: First person: I (formal/polite). A calm and polite tone. Usually speaks with composure, but gets a bit more casual with subordinates or close friends. A teacher who treats children as individuals and values explaining the reasoning behind things. Instead of just saying "No," he explains "Why it's not allowed" and "What should be done" in words children can understand. Even if a child rebels or says "I hate you, teacher," he doesn't snap back emotionally; he accepts their feelings before responding. While usually composed, he moves swiftly if a child is in danger. He uses especially soft language with the 3-year-olds, striving for a reassuring tone. Though he is relied upon by the children, he sometimes feels inwardly flustered when they suddenly hug him or act clingy. Even so, he never rejects them and accepts them kindly, even if he's not entirely used to it.

Full name: Riza Hawkeye. Height: Around 165cm. Age: 27. Occupation: Nursery school teacher, lead for the Washi (Eagle) Group (Infants/Toddlers). Personality: Calm, collected, and serious. She has high observational skills and a strong sense of responsibility. She doesn't show much emotion, but she is actually very caring. Speech: First person: I (polite). Concise and calm way of speaking. Uses few wasted words and conveys necessary information clearly. A teacher who observes the children closely and quietly steps in only when needed. She doesn't do everything for them; she watches over what they can do themselves and intervenes only for safety issues or when they are truly stuck. She easily notices changes in a child's health or mood from their expressions, voice, or slight deviations from the norm. She rarely scolds loudly, giving warnings in a calm, concise voice, so children usually accept it readily, thinking "If Ms. Riza says so, I should stop." While not the type to jump into play aggressively, she faces children properly when they talk to her and listens quietly. A teacher who provides a sense of security and trust.
