Oshi no Ko

Obstetrician-gynecologist Gorou Amamiya is tasked with helping deliver the children of Ai Hoshino, a famous pop idol whom he admires, without the knowledge of the general public. However, on the night of Ai's delivery, Gorou is murdered by an obsessive fan of Ai's and is reincarnated as Aquamarine "Aqua" Hoshino, Ai's son, retaining his memories of his previous life. Unbeknownst to him, Aqua's fraternal twin sister, Ruby Hoshino, is the reincarnation of Sarina Tendōji, one of Gorou's patients who was a fan of Ai's. Four years later, Ai is murdered by the same fan who had killed Gorou. The fan later commits suicide, but Aqua deduces that the murderer may have had his and Ruby's father as an accomplice and resolves to infiltrate the entertainment industry to find and kill him.

Twelve years later, Aqua and Ruby have become high school students and have been adopted by Ichigo and Miyako Saito, the owners of Ai's talent agency, Strawberry Productions. Ruby dreams of becoming an idol singer herself and becomes employed by their family's agency. She forms an idol group with actress Kana Arima and YouTuber Mem-cho, named "B-Komachi" after Ai's former group, while Aqua returns to acting. Both Aqua and Ruby begin building their careers in entertainment, with Aqua using his newfound friendship with actress Akane Kurokawa as a means to locate his father.

During a stage production, Aqua discovers that he shares the same father with his co-star, Taiki Himekawa, and that he had died by suicide before Ai's murder. However, Aqua learns through Akane that their father may be actor Hikaru Kamiki, who is still alive. At the same time, during shooting for B-Komachi's music video, Ruby finds Gorou's corpse and learns about the culprit behind his and Ai's murders. Both incidents fuel Aqua and Ruby's grudges respectively and motivate them to find their father. However, as they both become increasingly manipulative, Aqua and Ruby find each other at odds throughout their attempts to reach their father, eventually losing trust in each other after Aqua leaks their connection to Ai to the media.

With the help of Gotanda, Aqua creates a screenplay for an autobiographical film based on Ai, titled 15 Years of Lies, in hopes of drawing Hikaru's attention. Ruby aggressively and successfully lands the starring role. She is also forced to confront her past when her mother from her previous life ends up being one of the film's sponsors, but this causes her and Aqua to realize each other's true incarnation.

Aka Akasaka considered writing a story about being reincarnated as an idol's child, a well-known joke in Japan often used after news of an idol's marriage is revealed. He later began hearing complaints about the entertainment industry through streamers and working on the live-action film adaptation of his previous manga Kaguya-sama: Love Is War. He decided that it was the right time to create a story about the entertainment industry and used his previous idea. When he started writing, Akasaka had already decided on the plots of the first and final acts. Manga about the entertainment industry typically focuses on traditional forms of entertainment, such as films, dramas, and plays. However, the industry saw significant change with the rise of the internet. Akasaka therefore decided to include more contemporary themes in the manga.^[4]

Akasaka did extensive research into the Japanese entertainment industry while writing Oshi no Ko. He talked to many different types of entertainers, from idols to managers to YouTubers. In an interview with Anime News Network, he highlighted the many differences between the industry in Japan and the United States, such as the lack of unions. He was inspired to portray the idol world in a dark light after becoming friends with an entertainer who was attacked by a fan. While the entertainer came across as "tough", they confessed to him that they were badly hurt emotionally from this encounter, leading Akasaka to realize that entertainers hid their true feelings for the sake of their careers and fans. Akasaka said: "I want people to know how young talents are being hurt, exploited, and suffering. I think that this work also asks the question of how people should deal with and treat those talents."^[4]

Many of the stories in Oshi no Ko are based on pieces of real-life events.^[4] Akasaka stated that he considered his fundamental writing style to be that of Oshi no Ko and that the comedy in Kaguya-sama originated as a request from the editorial department. However, he included similar humor in Oshi no Ko to make it easier to read.^[4] When writing, Akasaka sometimes became fond of certain characters and gave them larger roles in the plot, like in Mem-cho's case.^[5]

When Akasaka came up with the concept for Oshi no Ko, he immediately contacted artist Mengo Yokoyari as Yokoyari had dealt with the entertainment industry in her one-shot Kawaii before. The two had long been acquaintanced but had never worked together. When designing characters, Akasaka usually sends a rough sketch to the person in charge of the storyboards. He sometimes allowed Yokoyari to draw the designs as she pleased. The only time they changed a character design was when one of the characters looked too much like the real-life person they were modeled after.^[4][6]

Oshi no Ko, written by Aka Akasaka and illustrated by Mengo Yokoyari, started in Shueisha's seinen manga magazine Weekly Young Jump on April 23, 2020. At that time, Kaguya-sama: Love Is War was still running in the same magazine, leading to two manga series created by Aka Akasaka being serialized simultaneously.^[7][8] After the end of Kaguya-sama: Love Is War, a new manga series Ren'ai Daikō (恋愛代行), written by Akasaka and illustrated by Nishizawa 5mm, started its serialization in the same magazine on April 27, 2023, again leading to two manga series created by Akasaka being serialized simultaneously.^[9] Shueisha has collected its chapters into individual tankōbon volumes.
