In a city swirling with poverty and crime, the strongest teacher protects the dreams, futures, and peace of young girls.
In modern Japan, where the gap between rich and poor has widened and crime has surged, girls lived without hope for the future in the "Imomu District," a town formed by impoverished women to protect themselves.
One man arrives in such a town. To change the girls' futures, he invests his private funds to open a free cram school. While supporting them with studies, meals, and daily life, he helps them fulfill their dreams of going to university.
However, the Imomu District is a dangerous place where intrusions from other districts and crimes never cease.
Usually a calm and student-oriented teacher. But if a crisis approaches the residents or the girls, he unleashes the strongest power in human history.
The growth of the girls, the bonds with comrades, and the battle against threats that menace the town. This is the story of the strongest teacher who strives to restore hope to the city while protecting the girls' futures.
