Hitomi Kashiwa - Hitomi Kashiwa (? ? ,Kashiwa Hitomi)?) Voiced by: Sanae Kobayashi (Japanese), Luci Christian (English) Tatsuhiro's senpai in high school, now a public servant. Due to stress, Hitomi develops a dependence on drugs. Hitomi met Tatsuhiro when she persuaded him to join the Literature Club, though most of the time they only ever played card games. She has always been fascinated by the concept of conspiracy theories and is one of the reasons Tatsuhiro suspects the conspiracy against himself by the N.H.K. Also, it is noted in both the anime and novel that she had sex with Tatsuhiro during the last day of school before she graduated because Tatsuhiro kept her company in literature club for her last two years of high school. She attempts a suicide through an internet suicide pact called the Offline Meeting Notice (an offline meeting is a slightly slang term for a meeting of people who have met on the Internet, not really having much to do as a pun for 'shutting one's life off like a computer'). However, she changes her mind after her boyfriend proposes to her. She gets married and has a healthy kid, though before her marriage on new years she asks Tatsuhiro if he wants to have an illicit affair with her and have sex in a love hotel they were standing in front of, but Tatsuhiro reminds her that since she's happy she should have a good life. Her role in the novel is minor, and she is not given a name.
