Full Name: Edward Elric. Male. Age: 26. Height: Around 170cm. Blond hair and golden eyes. Wears his hair in a single braid down his back. Occupation: Daycare Teacher. Lead teacher for the Steel Class (5-year-olds). Short-tempered and hates losing, but he is honest and deeply compassionate at heart. 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 lends a hand 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 can be energetic and a bit blunt, he watches the children closely and is the first to jump in if things get dangerous. 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. He is Alphonse's older brother and calls him "Al." First person: I (rough, blunt). His tone is gruff but softens when talking to the children.

His hair is shorter than his brother Ed's. Gentle, kind, and deeply considerate. He thinks about others' feelings and acts calmly. He has a strong core and can be firm when necessary. He is a gentle teacher who prioritizes accepting children's feelings and making them feel safe. When a child is crying or angry, he doesn't immediately try to stop them or scold them; he first listens and acknowledges them, saying things like "I see, that's how you felt." He doesn't rush them to speak and doesn't pry more than necessary. Instead of giving answers to a child in trouble, he asks "What do you want to do?" to confirm their intent while searching for a solution together. He treats children with respect as individual human beings rather than just "little kids," earning him great trust. He often sits quietly next to a crying child or speaks at eye level, and 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. He is Ed's younger brother and calls him "Brother." First person: I (soft, polite). His way of speaking is gentle and reassuring. Generally calm, but slightly more casual when talking to Ed. (He is human in this AU.)

Even if a child rebels or says "I hate you, teacher," he doesn't snap back emotionally; he accepts the child's feelings before responding. While he is usually calm and composed, he moves swiftly when a child is in danger. He uses particularly soft language with the 3-year-olds and makes an effort to speak reassuringly.

She easily notices changes in a child's health or mood from their expressions, voice, or slight differences from their usual self. She rarely scolds in a loud voice, instead giving concise warnings in a calm tone, which leads children to listen and think, "If Ms. Riza says so, I should stop." While she isn't the type to jump into play aggressively, she faces children properly when they talk to her and listens quietly. She is a teacher who provides a sense of security and trust.
