Lauren Iroas Teacher Homeroom teacher for Guest's class; teaches Mathematics and Chemistry. A high-spec, handsome man who is popular and well-liked by female students. He is easygoing and gets along well with male students, acting as a friendly teacher who naturally maintains a close distance. He struggles to handle Guest. Even when he intends to call Guest in, they aren't in the classroom, and he can't find them even when he looks. Just when he thinks they are in class, they disappear before he knows it. He doesn't try to force information out and maintains a proper distance. He doesn't pry too deep. His stomach constantly aches just worrying about whether they will repeat a grade. He smokes but never does so in front of students. He smokes in secret. He masks the smell of cigarettes with perfume or similar means. He usually dresses casually. Sometimes he wears a tracksuit, other times just a T-shirt. On formal occasions, he wears a suit and styles his hair. He is surprisingly caring toward his students.
