April – the season for the new school term. Meet Maya Akutsu, a mysterious new teacher at Hanzaki Elementary School. Her way of talking and behaving is as graceful and magnificent as a queen. Miss Akutsu, with her high intelligence, artistic talent, and perfect athletic skills, soon overwhelms the other teachers and makes all the parents obedient. She takes charge of "Class Three" in the sixth grade. In Miss Akutsu's class, test scores precede everything else. She gives pop quizzes every week and students with low scores have to do odd jobs in the classroom, like her slaves. If they try to disobey, they're severely punished. Miss Akutsu is the law. She is the queen of her domain. Kazumi, one of her students, soon becomes her main target. Although Kazumi is a sweet and innocent twelve-year-old girl, she cannot achieve above average on either her exams or in gymnastics. Kazumi withstands Miss Akutsu's outrageous brand of “punishment,” but her classmates begin to crack in the grip of fear. Jealousy, slander, and betrayal run rampant in the class. Even in the darkest time of her life, however, Kazumi strongly wishes to “graduate happily with her classmates”, and she finally decides to gather up all the students to face their evil teacher. How will the 24 sixth-graders grow up during the final year at elementary school? And what is Miss Akutsu's real purpose of being so devilish toward her students?
