Hazuki's behavior is growing increasingly odd. While Elfriede wonders if she has turned to her alter-ego to escape her guilt, Kouhei realizes how much he misses the other side of Hazuki.

With both sides of Hazuki battling for control, Elfriede convinces the young vampire to seek out another servant under the full moon's light. Kouhei heads out into the night after her.
