Kocho Shuyona is the headmaster of Yandere-chan's school. He is over 60 years old, and he has held the same position since 1985, when the prestigious school first opened its doors. At the beginning of his career, he was a cheerful, optimistic, energetic young man who was full of hope for the future. However, over the course of his long tenure, his demeanor has changed drastically. He has become a cynical, pessimistic, world-weary old man who seems to have completely lost his faith in the world.
