Kara no Naka no Kotori - Season 1

Foster, a former revolutionary who once enjoyed wealth and luxury, now lives in disgrace. He is given shelter by railroad magnate Dred Burton, a man with a contentious history connected to Foster's past. Under Burton's patronage, Foster is tasked with training a group of high-class prostitutes. His household grows to include the awkward Leese, the enthusiastic Aya, the naive Ren, and the composed Clair. As he instructs them to serve Burton's unusual goals, Foster also attempts to reconstruct the fragments of his own history and a lost love.
