Strike the Blood, (Light Novel) Vol. 05

Aya Tokoyogi and six other hardened magical criminals have broken out from imprisonment. Their goal--to completely erase the 'Witch of the Void,' Natsuki Minamaya, from existence. But they might even need to try very hard now that Natsuki has lost all her powers and memories, reverting to a child who depends on Asagi for everything. Meanwhile, as Yukina and Kojou search for a way to save the horrifically wounded Yuuna, help comes from an unexpected place, or rather, person. How these events will unfold in the Demon Sanctuary will depend on the action of the strongest vampire to ever exist, Kojou Akatsuki!
