While to the outside world Komori appears to be a polite and popular boy who wants to become a doctor, in reality he wants to change the world by sacrificing the educated in a similar manner to the Khmer Rouge's revolution in Cambodia. He tells Akira that he is going to build an everlasting empire, and that he will be king and she will be his queen. He dies at the hands of Hoshimaru after introducing immense fear into Akira and Shiina's hearts. His friends and living family do not know of his death; they believe he has simply gone missing. His disabled mother, unable to live on her own, dies soon after Komori's death. When Komori dies, everyone but Shiina and Akira believes that he went missing, and therefore the people do not know the truth about his situation.
