Yumoz is a former Shichibukai and one of the former Captains of the Destiny Pirates with Yobidashi S. King and Kyokai Uria. The majority of the time he is in-usage of his Devil Fruit, Ryōshin Ryōshin no Mi, meaning that he is using his two Consciences, Dark Yumoz and Light Yumoz. However, during his Shichibukai days, he used his fruit very sparingly, as he was monitored by the World Government very often, not wanting anyone to know of his Devil Fruit and its abilities.
