Although we’ve known about Hikaru’s involvement in Ai’s murder for some time, its true extent is revealed in Oshi no Ko chapter 160.
Initially masquerading as a lighthearted idol drama, Oshi no Ko quickly turned the story on its head. As Ai is stabbed by an obsessive fan and dies horribly in front of her children, we are left as traumatized as the characters in the story.
While this is already a dark moment, it becomes even darker when it’s revealed that Aqua and Ruby’s father ordered the murder. At that point, we knew nothing about him except that he was Ai’s ex, as she had never spoken about him.
Eventually, more information about Hikaru Kamiki is revealed, including his activity as a sociopathic serial killer. However, his character takes a 180-degree turn when he learns that Ai truly loved him and left him so as not to be a burden to him. After this, Nino was revealed to be the “final” villain of chapter 155.
This seems like a turning point for Hikaru until we get another shocking twist in Chapter 159. The last panel of the chapter shows Hikaru watching Ruby’s concert on the phone while Nino is caught by Akane and others. It would have been an innocent moment on his part if only Aqua hadn’t called him a liar.
The rest of the interaction continues in Oshi no Ko chapter 160. After Aqua accuses him of using weak people around him, Hikaru reveals that he never asked Nino and Ryosuke to kill Ai. He only told them about their relationship, as if he didn’t know how he had been fueling their obsession for years.
That day, Hikaru asked Ryosuke to deliver flowers to Ai on his behalf and gave him his address. This prompted the disturbed man to kill Ai before committing suicide. Throughout this time, Hikaru’s hands remained clean, with no evidence against him.
This revelation proves just how sinister and cunning Hikaru Kamiki is. After using so many people, he will eventually get what is due to him at the end of the manga, and most likely by his own son.
