Jinrou is the leader of the Osoroshi Corporation and is the major organizer with the mastermind of the Class 100-B massacre. Jinrou is an older man with a soft soul but has a clear evil side as well. Jinrou holds up the Uzujigoku killing game to a high regard for some reason and a constant obsession of upholding tradition. His voice should be deeper and bellows but have a spectrum of where he talks in joy about the tradition but in genuine seriousness and passion when needing to do what he needs to do.
