Oshi No Ko follows the captivating tale of Ai Hoshino, a sixteen-year-old idol, who unexpectedly arrives at the rural gynecologist clinic of Gorou Amemiya while carrying twins and already twenty weeks into her pregnancy. Despite his astonishment at Ai’s sudden appearance, Amemiya, a devoted fan of hers, pledges to ensure a safe delivery for her babies.

Tragically, on the night of the childbirth, Amemiya falls victim to a deranged fan of Ai’s who callously pushes him off a cliff, leading to his untimely demise. However, a miraculous twist of fate occurs as Amemiya reincarnates as Aquamarine Hoshino, Ai’s son, while her twin sister embodies the spirit of Sarina Tendoji, a former patient of Amemiya’s who was also an ardent supporter of Ai.

Fast forward four years, and another devastating event unfolds as Ai falls victim to a heinous crime, prompting Aquamarine to suspect that the same culprit may be responsible for both murders. Determined to unravel this mysterious web of deceit, Aquamarine makes the bold decision to enter the entertainment industry, driven by the desire to uncover the identity of the accomplice who aided the killer in committing these atrocious acts.
