Nejimaki Kagyu

Negizawa Kamo once tearfully promised his weak childhood friend

Kagyu Jubei that he would grow up to be a teacher who would not stand for bullying.

Several years later, as a teacher,

he meets Kagyu once more under strange circumstances to say the least.

While Negizawa was training to become a great teacher,

Kagyu (who, like most women, fell for Negizawa) polished her fists so that she could protect him when they met again.

Hilarity ensues as Negizawa strives to become the teacher he once dreamed of being and Kagyu protects his chastity from the numerous women who lust after his sweet behind.
