||Li Shengshun, Black Shinigami, BK201
The main protagonist and an elite Contractor with the Messier Code BK-201. Hei plays a gentle-hearted student from China named Li Shun Sheng, but when "working" he takes on the role of a seemingly (at first) apathetic and guiltless killer known also as The Black Reaper. Part of an organization of unknown ambitions known only as the Syndicate, Hei is searching for his sister Pai, whom he lost several years ago when the South American Heaven's Gate imploded. Hei's contract allows him to generate electricity, and he is hotly pursued by the Japanese government for his involvement in multiple assassinations. He acts as the spy/assassin of his team, swiftly dealing death without fail. His huge appetite and seeming lack of obeisance lend him more of a sense of mystery, even with his own team. He doesn't appear to have a remunition or regard for relationships outside of his team however. The only sense of concern and care seems to be revealed later on in the series, where Yin seems to be his main concern. Mysterious he is, but he discovers how he really feels about Yin in the second season.
