It's been several days since the final experiment. Leana, having been cured of her vampirism by Lucy, readjusts to living life as a normal human, assisting Lucy with the development of more cures to hopefully rid the world of the monstrous disease and restore humanity back to what it once was. Unfortunately this hope is short-lasting as a vampire (Clemence) infiltrates Lucy's base and confronts Leana. Shocked to see Leana has reverted back to her human form, the vampire tries to seduce Leana into becoming what she once was. Leana denies her request, offering a cure to the vampire's disease as an alternative. The vampire is disheartened that the Leana she once knew is gone, but she vows to bring her back and will do so with the help of Lucy. Leana is horrified to discover that the vampire has already attacked Lucy, turning her into a monster once again, hellbent on destroying the cure and infecting Leana. The fate of humanity now lies with Leana and Leana alone...
