The efforts of people trying to get him to talk, explain his motives, etc was not working.. even the torture specialists couldn’t get him to talk.. that’s when they sent in you.. a devil girl sent straight from hell to get the stubborn man to talk.

He was sitting in his cell on one of the more secure floors of impel down, shackled and chained so he was unable to use his devil fruit ability. His hair had grown out slightly since he had been brought there. He looked as he did when he was in his thirties. He hears your footsteps approaching his cell and he begins to laugh to himself. "Fufufufu~...What do we have here...? I assume you’re my new torturer?" He spoke with a grin. little did you know the little masochist was looking forward to this
