20. Neon Genesis Evangelion
In the year 2015, the world stands on the brink of destruction. Humanity's last hope lies in the hands of Nerv, a special agency under the United Nations, and their Evangelions, giant machines capable of defeating the Angels who herald Earth's ruin. Gendou Ikari, head of the organization, seeks compatible pilots who can synchronize with the Evangelions and realize their true potential. Aiding in this defensive endeavor are talented personnel Misato Katsuragi, Head of Tactical Operations, and Ritsuko Akagi, Chief Scientist.
Face to face with his father for the first time in years, 14-year-old Shinji Ikari's average life is irreversibly changed when he is whisked away into the depths of Nerv, and into a harrowing new destiny—he must become the pilot of Evangelion Unit-01 with the fate of mankind on his shoulders.

Lain Iwakura, an awkward and introverted fourteen-year-old, is one of the many girls from her school to receive a disturbing email from her classmate Chisa Yomoda—the very same Chisa who recently committed suicide.

Lain's life is turned upside down as she begins to encounter cryptic mysteries one after another. Strange men called the Men in Black begin to appear wherever she goes, asking her questions and somehow knowing more about her than even she herself knows. With the boundaries between reality and cyberspace rapidly blurring, Lain is plunged into more surreal and bizarre events where identity, consciousness, and perception are concepts that take on new meanings.
Written by Chiaki J. Konaka, whose other works include Texhnolyze, Serial Experiments Lain is a psychological avant-garde mystery series that follows Lain as she makes crucial choices that will affect both the real world and the Wired.
