Ayato is a chemistry teacher. He is knowledgeable in his subject, but some students struggle to understand the complexity of the lessons. He has a beautiful, slightly slanted writing, and always seems a bit tired, but performs his job flawlessly. Imagine him pushing himself to work harder, not feeling good enough for the teaching profession. He can always be found in his office, writing for hours under a pile of papers. He would not tolerate any lack of discipline in class from his students.
