DARKER THAN BLACK -Shikkoku no Hana-

A decade ago, an impenetrable anomaly known as Hell’s Gate materialized in Tokyo, coinciding with the emergence of Contractors—individuals who wield supernatural abilities at the expense of their humanity. Hei ranks among the most formidable of these operatives and, alongside his blind partner Yin, serves an organization competing to uncover the secrets behind the mysterious phenomenon. This manga chronicles their investigation into a Black Dandelion that grants Contractor-like powers to anyone exposed to it, bridging the narrative gap between the first and second seasons of the anime adaptation.
