Recently, Taito has been feeling very tired and often finds himself dreaming about a female vampire who claims to have given him a "poison." At times, he even believes that he can hear her voice while awake. However, following an accident that should have resulted in his death, Taitos perspective on life shifts dramatically, causing him to recognize the authenticity of his dreams.
