Uncovering the mystery of Ai's death in Oshi no Ko

One of the main mysteries of the series is the identity and motive of Ai Hoshino’s killer, who also murdered Aqua’s previous incarnation, Gorou Amemiya, a doctor who helped deliver the twins. Aqua, who retains his memories of his past life, vows to find and kill his father, who he suspects was involved in Ai’s death.

Aqua joins the entertainment industry in pursuit of the truth behind his father’s identity and also to find the killer responsible for the death of Ai and his former self. Years pass as Aqua and Ruby move further up in the industry, trying to uncover this mystery.

When Akane Kurokawa, Aqua’s girlfriend at the time, attended the Japan Film Awards after winning the ‘New Actor Award,’ she received flowers from someone resembling Aqua.

She finds out from Toshirou Kindaichi that the sender of the flowers was a former theatre actor from Lalalie Theatrical Company and is now the owner of a production company. After watching a footage of the former actor, Hikaru Kamiki, Akane was convinced that he must be Aqua and Ruby’s father.

However, she decides not to tell Aqua of this finding and looks into Kamiki on her own. But Aqua eventually finds out because he has been shadowing Akane’s movements with a tracker he secretly implanted on one of her personal items. This incident strains their relationship, and they have an argument about it, which ends with Aqua breaking up with Akane to seek revenge against their father.

Currently, in the storyline, Aqua has already figured out his father’s identity and starts to plan his revenge for his mother’s murder. Fans will have to wait and see as the story unfolds to reveal what the author has in store for its characters.
