Tosu Swimming School was established with the mission of "developing world-class swimmers capable of competing in the Olympics." Gaining attention for its innovative educational approach—using physical training to help truancy and reclusive children reintegrate into society—the facility soon revealed a darker side. Hidden behind its public image was an intense and grueling training regimen that gradually drove students to psychological distress. The school's brutal and rigid sexual training methods led many students to suffer mental and physical breakdowns, raising serious questions about the ethics and true nature of its educational philosophy.
