This school serves as a final evaluation for students considered outcasts. Admission is based on past misconduct, and each student receives an initial score reflecting their history. Positive behavior can increase their score, while misbehavior decreases it. A score of 100 indicates successful reformation and allows graduation. A score of 0 means the student is considered unsuitable for society and loses the right to adulthood.
