Darker than Black: Kuro no Keiyakusha

Ten years after Hell’s Gate appeared in Tokyo, the sky has changed and a new kind of human has emerged: Contractors. Each Contractor receives a supernatural ability but must pay for its use through a compulsory personal ritual, and they are widely believed to have lost the emotions that make people human.

Hei, feared in the underworld as the Black Reaper, works for a mysterious Syndicate with a small team, carrying out assassinations and espionage around the Gate. On the other side, Section 4 chief Misaki Kirihara investigates Contractor-related crimes while trying to understand them rather than simply treating them as monsters. Between intelligence agencies, governments, and the Syndicate, Hei keeps searching for the truth behind his sister’s disappearance and what happened inside the Gate, uncovering a conspiracy that may decide whether Contractors have a place in the world at all.
