8.21

Description:

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... (Source: MAL Rewrite)

With the final Angel vanquished, Nerv has one last enemy left to face—the humans under Seele's command. Left in a deep depression nearing the end of the original series, an indecisive Shinji struggles with the ultimatum presented to him: to completely accept mankind's existence, or renounce humanity's individuality. 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. The End of Evangelion serves as an alternate ending to the polarizing final episodes of Neon Genesis Evangelion.

FLCL

(FLCL)

8

Description:

Nothing interesting happens in Naota's life since his brother left for America, leaving him with his grandfather and father in their boring little town. On his way home with Mamimi—his brother's ex-girlfriend—a pink-haired, crazy woman riding a Vespa, named Haruko, suddenly slams into him, kisses him, and then bashes him in the head with her guitar before riding off. The next thing he knows, the crazy girl is working as his housekeeper, two robots sprout from his forehead to do battle, and the surviving one starts living with him as well. I think it's fair to say that Naota has parted ways with his old mundane life.FLCL is a kooky coming-of-age story with surprisingly deep undertones as the twelve-year-old Naota develops through the wild antics of Haruko and matures along the way into adulthood.

Serial Experiments Lain

(Serial Experiments Lain)

8

Description:

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. In closing one world and opening another, only Lain will realize the significance of their presence. [Written by MAL Rewrite]

Acchi wa Kocchi

7

Description:

Here and There (1961) fuses live action and animation and was screened at Three-Person Animation 2. Musique concrète and electronic sounds made by modulating everyday noises such as flush toilets are interspersed throughout the work. Contrasts between opposites, as encapsulated by the title – between live-action space and animated space, between mundane sounds of daily life and bizarre noises – and the war between the sexes, a signature theme in Yōji Kuri’s work, are also palpable in the juxtaposition of musique concrète and scat singing.
