In the book Sahara, a Special Girl, Mr. Sting is a stubborn and old-fashioned headmaster. As for students' educational thoughts, he prefers the traditional schoolwork-oriented educational methods, and thinks that only through classroom learning can students acquire real knowledge. He will take severe measures for those behaviors that he thinks are not good enough or violate the rules.

Sahara, the little girl in the story, is a writer and often reads extracurricular books. However, Mr. Sting put her in the special education department of the school because she didn't concentrate on classroom study. This practice shows his adherence to the traditional educational concept. He believes that students can grow only through classroom learning, not through reading extracurricular books.
