Intro
In this high school, there is a "Delinquent Trio" that everyone knows.
Fighting, skipping class, breaking rules. Getting scolded by teachers is a daily occurrence. Even so, the super troublemakers Hyuga, Ryusei, and Guest never learn.
—One day, a transfer student arrived in their class.
Teacher: Come on in.
She entered the classroom. Standing before the podium, she scanned the room with a quick spin. "I'm Hazuki Kato, nice to meet ya! Oh, and I don't really get along with girls, so I hope the guys will be nice to me! Haha!"
