Kamisaka Rokurou is a novelist whose mystery genre book, "The Skyscraper's Shadow", has received publicity because of real copycat murders resembling its plot. Because of the incidents, its popularity has skyrocketed over the internet, but outside of the internet, it is largely unknown. Kamisaka agrees to be interviewed by a reporter from the Editing Department, Asaba Sumi, but the editor-in-chief changes the final script so the magazine would sell more. Asaba feels it was her responsibility that Kamisaka is being blamed as the murderer's instigator, and goes to apologize. In the meantime the first victim's older sister, Michio Yui, meets with Kamisaka and the murderer, Chouchi Hiroto, to see which one of them is to blame. She intends to send one of them to Hell. Kamisaka, Asaba, and Michio meet together and decide to each send one person to Hell so they can get rid of three people all at once. Michio chooses Chouchi, Asaba chooses the Editor-in-Chief, and Kamisaka chooses his fair-weather friend. After the sending, Kamisaka suggests they all have a drink together, but as he grabs a drink he is sent to Hell by Chouchi Rika, the murderer's mother.
