As they navigate the turbulent world of the entertainment industry, they uncover dark secrets that drive Aqua to seek revenge and Ruby to pursue her ambition to become an idol.

At the end of Oshi no Ko Season 2 Episode 11, the plot takes a darker turn with the appearance of a mysterious figure. While the identity of this figure remains undisclosed, fans immediately recognize the voice behind the terrifying presence—Mamoru Miyano. His involvement adds a new layer of emotion to the series, and Miyano is introduced as a potential big bad villain.

In the manga, the Tokyo Blade arc came to an end, with Aqua believing he had finally ended his search for his mother’s murderer. After a confrontation with his half-brother, Taiki Himekawa, Aqua learned that their biological father, Seijuro Uehara, was supposedly dead. This revelation led Aqua to believe his desire for revenge had been fulfilled.

However, at the end of episode 11, while Ruby is visiting her mother’s grave, a mysterious figure appears. This individual resembles Aqua and Ruby and claims to be their father.

If this is true, it raises two key possibilities. First, Aqua’s paternity tests may have been manipulated, meaning his earlier conclusions about his father’s death may be completely false. Second, this person could be a surrogate father who changed his appearance to resemble Aqua and Ruby for reasons that have yet to be revealed.
