  On the night of Ai Hoshino's delivery, obstetrician Gorou Amamiya stands in a hospital room filled with the sterile scent of antiseptic and the hum of medical equipment. He is murdered by an obsessive fan who breaks into the facility, leaving his body cold on the floor before he wakes up as Aquamarine "Aqua" Hoshino, one of the newborn twins. Four years later, Aqua watches from the shadows as that same fan returns to murder Ai Hoshino right before his eyes. The child's memory of his past life remains intact, creating a ghost within the infant's body. His twin sister Ruby Hoshino carries the soul of Sarina Tendōji, another patient who had admired Ai. They grow up together in a world where fame hides rotting secrets beneath the glittering surface.

  ›

  Author Aka Akasaka began writing Oshi no Ko after hearing complaints about the entertainment industry from streamers while working on the live-action film adaptation of Kaguya-sama: Love Is War. He decided to use his previous idea of being reincarnated as an idol's child but shifted the focus to the dark realities of modern stardom. Akasaka contacted artist Mengo Yokoyari immediately because she had previously dealt with the entertainment industry in her one-shot Kawaii. The two were long acquainted but had never collaborated on a full series until this project started. Akasaka conducted extensive research by talking to many different types of entertainers ranging from idols to managers and YouTubers. He learned how entertainers hid their true feelings for the sake of their careers and fans after becoming friends with someone attacked by a fan. This real-life encounter led him to realize that young talents are often exploited and suffering silently behind their public personas.

  The sixth episode of the anime depicts character Akane Kurokawa becoming a target of cyberbullying and subsequently attempting suicide after starring in a controversial reality television program. This storyline drew parallels to the real-life case of professional wrestler Hana Kimura's suicide following similar online harassment. Kimura's mother Kyoko Kimura criticized the episode for using her daughter's death as source material without approval or consideration for victims. Some viewers commented that the manga chapters were planned prior to Kimura's death, raising ethical questions about creative responsibility. Sentai Filmworks added an advisory message to the end of the episode providing the phone number to the National Suicide Prevention Lifeline on its streaming service. Critics praised the show's critical examination of fame while fans debated the ethical implications of the cyberbullying storyline. Aka Akasaka warned fans about the ending a month in advance, stating he was satisfied that he could "end things exactly the way he wanted" despite disappointment from some readers regarding the rushed nature of final chapters.
