Darker than Black Season 1: The Black Contractor
DARKER THAN BLACK ー黒の契約者ー (Dākā Zan Burakku -Kuro no Keiyakusha-)


Ten years ago, a mysterious spatial anomaly is now known as “Heaven’s Gate” appeared in South America, shortly followed by the opening of “Hell’s Gate” in Tokyo altering the sky and wreaking havoc on the landscape. The real stars disappeared, replaced by false stars. During this time, people possessing various special abilities—called “Contractors”—emerged, each capable of different supernatural feats. Each Contractor has a corresponding fake star, which reacts to their activities. As such, Contractors are usually identified by their star’s Messier catalog number. Kept secret from the masses, these individuals are known to murder in cold blood, smothering unnecessary emotions with logic and rationality. Their incredible abilities, however, are gained at the cost of their humanity; Contractors are thus named because of an involuntary compulsion to “pay the price” each time their power is used, which can range from eating particular foods or completing meaningless tasks, to self-harm and change their bodies in peculiar ways. Various nations and organizations around the world train and utilize Contractors as spies and assassins, resulting in violent battles for valuable objects and information.

TL;DR Review

Darker than Black, also known as Darker than Black: The Black Contractor, is an anime television series created and directed by Tensai Okamura and animated by Bones.

The action and animation for Darker than Black are top-notch. Combat animation is fluid, if not a bit short. Fights are not drawn out, so it may be over before you know it. Even if you have some awesome power, one mistake and you are as good as dead.

I especially like the first ending song “Tsukiakari” by Rie fu and the second opening theme “Kakusei Heroism ~The Hero Without A Name~” by An Cafe. The music for the series is composed by Yoko Kanno.

The characters are interesting, even character that lacks emotion like Yin is entertaining to watch. If you can’t tell by now, Hei is one of my favorite characters. Despite being a Contractor, which should lack emotions. He appears to be displaying some humane traits.

However, there are a few characters that seem to be there only for comedy relief and stand out like a sore thumb. I am speaking of course about the private eye and his assistant. Most of the arc that involve them tend to feel like filter content.

The first season contains multiple mini-story arcs. Some arcs develop the character and progress the plot along while many of the other does not. You can mix most of the arc in any order and it wouldn’t make a difference.

Despite all my nitpicks, Darker than Black is one of my favorite series. I highly recommend this series to the fan of dark fantasy action. Darker than Black contains graphic violence, some nudity, and some suggestive themes/dialogs. Intended for young adults.
