19. 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.
Written by Hideaki Anno, Neon Genesis Evangelion is a heroic tale of a young boy who will become a legend. But as this psychological drama unfolds, ancient secrets beneath the big picture begin to bubble to the surface...

Meanwhile, at the core of a compromised Nerv, Gendou Ikari and Rei Ayanami approach Lilith in an attempt to realize their own ideals concerning the future of the world.

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 has neither the desire nor the experience to handle even basic technology; yet, when the technophobe opens the email, it leads her straight into the Wired, a virtual world of communication networks similar to what we know as the internet. 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.

And in large ways: the spiral marks on people's bodies, the insane obsessions of Shuichi's father, the voice from the cochlea in your inner ear.

8. Kago Shintarou Anime Sakuhin Shuu
In these jokey short films, many of them crudely animated, Kago's sick sense of humor reaches its full heights of absurdity. There's a playful surrealist sensibility to Kago's work, as well as a tendency to revel in the ridiculous, the crude and the disturbing. His work straddles a weird boundary between avant-garde experimentation and low-brow fart jokes—the punchline of one of these films is literally an oozing torrent of shit—although, admittedly, his videos seem to lean a bit more heavily towards the fart jokes than his comics. But hey, who doesn't appreciate a good fart joke once in a while?
Kago Shintarou Anime Sakuhin Shuu has finished airing and it has 15 Episodes. It is also Known as: 駕籠真太郎アニメ作品集, Short Animation of Shintaro Kago

THE END is an opera birthed out of the collaboration between Keiichirou Shibuya, director and script writer Toshiki Okada, and illustrator YKBX.
