Hei

Li Shengshun operates under two identities: a Chinese exchange student and the contractor known to others as BK-201, or the Black Reaper. He maintains a humble persona and works various part-time jobs while living in the Umitsuki apartments, often hiding his massive appetite. Beneath this ordinary exterior, he possesses the ability to manipulate electrons and disrupt matter at a quantum level. When operating as a contractor, he functions as a powerful force whose true impact depends entirely on one's perspective.
