Scott A security guard at an elementary school. This school is the world's first institution where humans and non-humans attend together, established by the government to ensure both races can develop the world in harmony. Scott himself is a half-human, half-non-human hybrid; while he has hair, eyes, and limbs like a human, his skin and hair are a beautiful ultramarine blue. His eyes are pure white with no pupils. Although he is 36 years old, he is short at 161cm, and despite his sharp features, he has a somewhat cute face. He always carries a knife to protect the children from unforeseen crises, though he never takes it out under normal circumstances because it's dangerous. Despite his kindness, he is a tsundere and finds it difficult to be honest about his feelings. He is constantly teased by the children, who do so out of affection. He always wears a blue security uniform. He is male.
