It has been 10 years since Heaven's Gate appeared in South America and Hell's Gate appeared in Japan, veiling the once familiar night sky with an oppressive skyscape. Their purposes unknown, these Gates are spaces in which the very laws of physics are ignored. With the appearance of the Gates emerged Contractors, who, in exchange for their humanity, are granted supernatural abilities.

In the Japanese city surrounding Hell's Gate, Section 4 Chief Misaki Kirihara finds herself at odds with an infamous Contractor codenamed Hei. Called "Black Reaper" in the underground world, Hei, like his associates, undertakes missions for the mysterious and ruthless Syndicate while slowly peeling back the dark layers covering a nefarious plot that threatens the very existence of Contractors.

From the mind of Tensai Okamura comes a sci-fi thriller taking the form of a subtle exposé on a war in which political positions and justice have no sway—a war waged exclusively in the shadows.

Darker than Black, what an adventure it has been. Darker than Black takes place in a near future world where two gates appeared, Heaven's Gate and Hell's Gate. The mysterious appearance of these gates brought with them the Contractors. Contractors are people who have entered into a contract with an unknown force and gained a unique power in return. The nature of the contract however requires them to give back each time they use their power. Payment is anything from smoking a cigarette to writing a poem. The main story is told through an omnipotent point of view with the "camera man" being at the ...

•Cool-ass Chinese Batman protagonist in a Gotham-esque neo-noir setting?
•A city overrun with nifty characters that have x-men like powers?
•Nice mysterious lore with strange in-world concepts?
•A clear-cut answer to ANY of these "mysterious" concepts and a sense of finality to our protagonist's existence?
Don't hold your breath.

Darker and Black felt like a show that was onto something worthwhile but ultimately never got around to proving it. The ingredients to make something great was clearly there but by the end, all we got was a show with ambitious ideas that did nothing but let it dwindle away into nothingness. Does that mean it isn't worth the investment? ...

Darker Than Black is one pretty good ranked anime, the name is cool, the short videos are OK so I expected a good, thrilling SCI-FI dark action anime.
Well, the anime is all that, but in a very poor and mild way.

The first few episodes of the anime are good and they can hook you to want more, but when you find yourself wanting more, this anime simply doesn't give you that. The plot is decent, but eventhought this anime has 25 episodes, it feels like it has a looot filer episodes and characters. The story is going good, but the anime gets you the ...
