Oshi no Ko manga was serialized in Weekly Young Jump beginning in April 2020. The anime adaptation was announced in June 2022, with its first episode released on 12 April 2023 in a special 82-minute theatrical screening format. The series has drawn attention for its realistic and critical portrayal of the behind-the-scenes of the entertainment industry.

The series is set in the modern Japanese entertainment world, focusing on the idol industry, reality television, the drama sector, and theater. Although it begins with a supernatural element—reincarnation—the rest of the universe is grounded in realistic depictions of industrial standards, fan culture, and media manipulation.

Gorou Amamiya, a gynecologist working in a rural town, learns that his favorite idol, Ai Hoshino, is pregnant. On the night of her childbirth, Gorou is mysteriously murdered and is reborn as one of Ai’s twin children, Aquamarine Hoshino. Her other twin, Ruby Hoshino, is similarly reborn as Ai’s daughter. After Ai’s tragic assassination, the story follows Aqua’s infiltration of the entertainment industry to uncover the true culprit behind her mother’s murder and Ruby’s pursuit of becoming an idol in her mother’s footsteps.

The emotional arcs of the characters are conveyed through the following voice cast:

• Ai Hoshino: Idol of the group "B Komachi".
• • Voice Actor: Rie Takahashi (JP) / Donna Bella Litton (EN)
• Aquamarine (Aqua) Hoshino: A cold and intelligent young person seeking revenge for his mother’s death.
• • Voice Actor: Takeo Otsuka (JP) / Jack Stansbury (EN)
• Ruby Hoshino: A cheerful and idealistic young girl who dreams of becoming an idol.

• Themes: The dark side of the entertainment industry, social media bullying, the use of lies as a protective mechanism (the idol culture philosophy of “a lie is love”), and professional acting techniques.
• Narrative Style: The series contrasts its bright and vibrant color palette with dramatic and suspenseful scenes. The motif of “stars in the eyes” serves as a symbolic device representing characters’ charisma or emotional emptiness.

• Season 1: Covers Ai Hoshino’s rise to fame, her death, and Aqua’s initial steps into the entertainment world (including reality TV behind-the-scenes).
• Season 2: Focuses on the world of 2.5D stage plays, exploring the inner workings of theater.
• Differences: The anime visually translates internal monologues and technical explanations from the manga while maintaining its pacing. In particular, animation quality and original songs (such as YOASOBI’s “Idol”) enhance the musical performances.

• Musical Achievement: YOASOBI’s opening theme “Idol” became the first Japanese-language song to reach number one on the Billboard Global (excluding the U.S.) chart.
• Awards: The series has won multiple Anime Awards in 2023 and 2024 in categories including Best New Series, Best Opening, and Best Drama.
