One month after transferring to a notoriously troubled school in the prefecture, Yuko was struggling with the students' misbehavior. One day, determined to rehabilitate them, she decided to revive the rugby club, which was on the verge of being disbanded. Initially resistant to Yuko's persistent persuasion, the students gradually began to join the team as they were swayed by her alluring creampie coaching. With the team finally gathering enough members, the rugby club started thriving once again—except for Yamada, known as the school's worst delinquent, who remained emotionally closed off. Yuko faced his stubbornness head-on, attempting to slowly open his heart through creampie education.
