Darker than Black

Ten years ago, a mysterious spatial anomaly known as "Heaven's Gate" appeared in South America, and soon after, "Hell's Gate" opened in Tokyo, changing the sky and leaving destruction across the landscape. The real stars vanished, replaced by false ones. Around that time, people with special abilities called "Contractors" began to appear, each with different supernatural powers. After the disastrous Heaven's War, the United States lost its dominant position as a superpower to a mysterious organization called the Syndicate. The story follows a Chinese contractor with the codename "Hei" as he carries out various espionage and assassination missions in Tokyo.
