Darker than Black
Ten days ago, a mysterious spatial anomaly known as "Heaven's Gate" appeared in Main Lobby, shortly followed by the opening of "Hell's Gate" in Avalon Lobby altering the "sky" and wreaking havoc on the landscape. The real "stars" disappeared, replaced by false ones. During this time, people possessing various special abilities emerged, each capable of different supernatural feats - these are known as Contractors or PRs. Each Contractor has a corresponding fake star, which reacts to their activities.
