Yamazaki Hajime

He is a teacher at Kisaragi Academy, and teaches English to Class 2-9. He has a deep affection for his students, and with his sympathetic behavior he has given many of his former students dreams and hopes of going to Yale. Yui is one of his former students. These days he is often away on trips to academic conferences and leaves Yui in charge of Class 2-9 as the Vice homeroom teacher. Seeing his students having fun always makes him smile happily.
