Tokyo Girls Destruction

In a future where Japan’s prime minister sees women’s culture as corrupted, she establishes a girls-only academy on an artificial island in the Pacific to restore traditional femininity. Amesu Kumi transfers there to investigate the mysterious death of her older sister, Towa, who was a student at the school. Kumi’s only lead is the name Burai Sachiko, found on Towa’s phone. She soon discovers that after classes, the academy becomes a battlefield, where the girls fight each other in brutal struggles to survive.
