Hikaru Kamiki is the main antagonist of Oshi no Ko. He is the man who fathered Aqua and Ruby with Ai Hoshino and the person who leaked Ai’s address to a disgruntled fan, leading to her death and prompting his son to devote his life to tracking him down and getting revenge. He is the president of Kamiki Productions.
Hikaru proves to be extremely polite and even somewhat gentle and submissive as a child. Because Hikaru was sexually abused by Airi Himekawa during his childhood, he seems to have extreme issues with attachment and trust. He is shown as a very reckless and emotional individual. It is also mentioned that he despises his good looks because he believes it is the reason why different people prey on him.
