Also known as: クロード
"Guild master of the Ikebukuro Guild and owner of the underground Colosseum, where Transients gather in an undisclosed, Ikebukuro-based location. He is half Japanese and half Italian. Though he's proud, and gifted with natural leadership abilities, he seeks the slave-come-bridegroom (regardless of gender) who shall arise from the groveling masses to become his. He dislikes any woman who bears a resemblance to his mother."
