Kyokutou Prison
極東プリズン
In a high school designed for society's worst delinquents, students are given a score based on their past crimes. The school serves as a final test to determine whether they can become functioning members of society. By behaving properly, students can earn points, while any wrongdoing lowers their score.
Those who reach 100 points are deemed reformed and allowed to graduate. However, students who end up with zero points are ruled unfit for society and lose their right to become adults. As the students navigate this harsh system, they must fight to survive and prove their worth.
