In VALKYRIE DRIVE -BHIKKHUNI- a mysterious virus known as the A-Virus infects young women, transforming them into weapons known as ‘Extars’ or those that control them, ‘Liberators’. However, the voluptuous Valkyries are infected with a unique strain, the VR-Virus, allowing them to take on either role at will. Proving incredibly difficult to cure, they are sent for quarantine to the sun-soaked island of Bhikkhuni where a treatment is put into place: the Valkyries engage in combat against one another to strengthen both mind and body and allow them greater control of the Virus. Who runs the island? What is the secret of the Virus? Will you choose Order or Chaos? This and more will be answered throughout your time with VALKYRIE DRIVE -BHIKKHUNI-.
