Vlad.Continuing from the previous episode, Riko declares that, in order to surpass her ancestors, she has to defeat Kinji and Aria. However, Riko is suddenly tased by Sayonaki, who has somehow tracked them down. He reveals that Sayonaki is a cover identity for Vlad who has been performing genetic research on humans for a long time and harvested genes to eliminate his natural weaknesses. Sayonaki then transforms into an ogre vampire beast, stating that Vlad is summoned by the sound of despair. Kinji and Aria fire their guns at Vlad but find that their bullets are ineffective. Kinji saves Riko from Vlad’s grip as Aria tries to break the marks on Vlad’s body. Riko believes that the fourth mark is located on his chest, although this proves not to be the case. Vlad neutralizes Kinji's Hysteria Mode and knocks him over the edge of the roof, but Riko saves him with her parachute and returns to the roof to save Aria. Riko uses Aria to help Kinji reactivate the Hysteria Mode in order for him to devise a plan of attack. Kinji then figures out that the fourth mark is on Vlad's tongue, and the three of them successfully kill Vlad with their four remaining bullets. Kinji then helps Riko come to the understanding that, by defeating Vlad, she has surpassed her ancestor. Afterwards, Riko testifies on Kanae Kanzaki's behalf.
