Nao Matsuzaki is a pop idol whose music video for the song Shiroi yo. is used as the cursed videotape at the center of the story. When the main character Kazuyuki Asakawa plays the tape he finds at a cabin, he is surprised to see a music video by Matsuzaki instead of the expected horror imagery. In the context of the series, Matsuzaki appears as herself, a real-life singer whose work becomes unwittingly linked to the supernatural curse. She makes a brief cameo appearance in the final episode. Beyond this, little is revealed about her personal background, personality, or motivations within the narrative; her function is primarily as a plot device. She has no direct interactions with the main characters aside from being the face of the cursed video. There is no character arc or development for her, and she possesses no special abilities.
