Plot
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. Four years later, Ai is murdered in front of the twins by the same fan who 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 Miyako Saitō, the owner 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.
