Oshi no Ko

Staffel 1

In the entertainment world, celebrities often show exaggerated versions of themselves to the public, concealing their true thoughts and struggles beneath elaborate lies. Fans buy into these fabrications, showering their idols with undying love and support, until something breaks the illusion. Sixteen-year-old rising star Ai Hoshino of pop idol group B Komachi has the world captivated; however, when she announces a hiatus due to health concerns, the news causes many to become worried.
As a huge fan of Ai, gynecologist Gorou Amemiya cheers her on from his countryside medical practice, wishing he could meet her in person one day. His wish comes true when Ai shows up at his hospital—not sick, but pregnant with twins! While the doctor promises Ai to safely deliver her children, he wonders if this encounter with the idol will forever change the nature of his relationship with her.

Staffel 2

With the help of producer Masaya Kaburagi, Aquamarine „Aqua“ Hoshino and Kana Arima have landed the roles of Touki and Tsurugi in Lala Lai Theatrical Company’s stage adaptation of the popular manga series Tokyo Blade. Co-starring with them is Aqua’s girlfriend, Akane Kurokawa, who plays Touki’s fiancée, Princess Saya. Due to the fanbase preferring Tsurugi as Touki’s love interest, Saya has made fewer and fewer appearances in the manga, making it difficult for Akane to fully immerse herself in the role. Her struggles are compounded by differences between the play’s script and the original work—differences that also frustrate Tokyo Blade’s author, Abiko Samejima.
Aqua, however, is more concerned with his personal goals than he is with the play. He has only one objective in mind: to grow closer to director Toshirou Kindaichi and find out what he knows about Aqua’s mother, Ai.
