Umineko no Naku Koro ni:
He is the president of a company who has ties with Rudolf's and Hideyoshi's companies. Ange goes to question him about everything he knows of the Rokkenjima murders, despite suspecting that he may betray her. Although he had been hired by the Sumadera family to stall Ange and allow them to take control of her wealth, he proves himself to be Ange's fundamental ally in the end and allows her to escape, hiring Amakusa to protect her. He influences Ange greatly in her battle against Beatrice, particularly his belief that truth can only be obtained through love.
