Miharu Kayama is a character who appears in the first season of Jigoku Shōjo, notably in the episode Sweet Temptation. She is an ordinary young woman who becomes consumed by a deep and bitter grudge against someone named Kiriko. Driven by her desire for vengeance, Miharu learns of the Hell Correspondence website and submits a request to have Kiriko sent to hell. After making the request, Miharu is taken to the Twilight realm, where she meets Ai Enma, the Hell Girl. In a desperate plea, she begs Ai to carry out the sentence. Ai presents Miharu with a black straw doll and explains the terms of the contract: if she pulls the red string, Kiriko will be damned, but Miharu’s own soul will also be condemned to hell after her death. Miharu’s motivation stems from the torment she has suffered at Kiriko’s hands, though the specific nature of their conflict is not elaborated upon in the episode. Her personality is marked by intense resentment and a willingness to sacrifice her own afterlife for the satisfaction of revenge. In her role within the story, Miharu serves as the client of the week, a human caught in the moral dilemma of the series’ central supernatural system. Her story intersects with the ongoing investigation by Hajime Shibata and his daughter Tsugumi, who can perceive the supernatural events surrounding the Hell Correspondence. Tsugumi has a vision of Miharu holding the straw doll, which prompts Hajime to attempt to intervene and dissuade her from pulling the string. However, like many clients in the series, Miharu appears resolved in her decision, and her ultimate fate is left to the viewer’s interpretation. No significant character development occurs beyond her episode, and she possesses no special abilities; she is an ordinary human whose life is irrevocably altered by the choice she makes.
