The Mastermind Behind Ai's Death? The Mysterious Man's Suggestive Remarks Are Too Ominous in "Oshi No Ko" Episode 22

A key person in the incident that took the life of Ai Hoshino (CV: Rie Takahashi) has appeared!? In the final moments of anime "Oshi No Ko" Episode 22, Ruby (CV: Yurie Igoma), who came to visit her mother's grave, passed by a mysterious man.

The twins Aqua (CV: Takeo Otsuka) and Ruby lost their mother Ai, who was an idol, when she was stabbed by a stalker in their childhood. Since then, Aqua has theorized that his father, whose identity he doesn't know, provided information to the stalker and instigated the incident. He has lived thinking only of taking revenge on his father, who is likely the mastermind behind everything. However, he learns from Taiki Himekawa (CV: Koki Uchiyama), who turned out to be his half-brother, that his father had long since departed from this world.

Just when it seemed Aqua's revenge story would come to an end, the narrative takes a sudden turn at the end of Episode 22. Ruby, who had visited Ai's grave, passed by a man wearing sunglasses with hair color similar to hers on her way back. The man secretly looked at Ruby and muttered, "Ruby Hoshino, you've grown into a beautiful woman," and when he came before Ai's grave, he made a cryptic statement: "As expected of my child with you."
