Serial Experiments Lain

Present day. Present time. The day after a classmate commits sucide, 13-year old Lain Iwakura receives an e-mail from the dead girl. A wave of deaths follow, mostly involving young people. Lain is haunted by visions, and soon she finds that the line between the real world and the wired world have begun to blur. As Lain translates herself into the Wired to investigate the suicides and deaths, she finds that there seems to be another Lain, who is totally unlike herself. Who is Lain? Or rather, what is Lain? Is Lain even a person?
