My hero is Mr. Shu Mizutani. He is a teacher, who is trying to protect children from violence, drugs, and so many things. My dream is to be an English teacher but I never want to be the kind of teacher who says 'The students have only to study.' I mean, I would like to come in contact with children dearly from the heart.
Nowadays I hear that the communication between teachers and students is not good. To make matters worse, sometimes teachers commit a crime involving children.
However, Mr.Mizutani, my hero, is the opposite from such a case. He patrols downtown every night. He guides a lot of children who are in danger of despair. And, he was often involved in fights. But he never gets angry with children. He never blames children, either. He thinks that children are always victims.
His thinking was published as 'Yomawari sensei' series. Many people who have a longing to be a teacher should read his books.
