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.

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]

Yami Shibai

(Yamishibai: Japanese Ghost Stories)

6.88

Description:

The mysterious, yellow-masked Storyteller is a man whose true name and origin are both unknown. He appears at dusk where children gather and recites sinister tales based on Japanese urban legends, to which his young audience eerily intakes. However, the Storyteller is no ordinary teller of tales. He incorporates a kamishibai, a traditional paper-scrolling device, to add visuals to his already demented narration. A series of short horror stories, Yami Shibai begins with a bachelor who, after moving into a new apartment, immediately starts sensing a malevolent glare being pressed into him. A single talisman rests on his ceiling, but he has no way of knowing it is one of the few safeguards that separate him from a bottomless pit of suffering. Each story is more terrifying, more appalling, and more sickening than the last as the Storyteller's audience find themselves being sucked into the vicious world of his words.
