Tetsuro Okonogi  

, 小此木 鉄郎

The president of a company with connections to Rudolfs and Hideyoshis companies has ties to Ange. Despite her suspicions that he may betray her, she questions him about the Rokkenjima murders. Although hired by the Sumadera family to delay Ange and seize control of her wealth, he proves to be a crucial ally to Ange in the end. He allows her to escape and hires Amakusa to protect her. His appearance resembles that of Okonogi from Higurashi no Naku Koro ni, though their personalities differ slightly.
