Oken serves aboard the Quin Zaza as part of its draking crew. He sports messy brown hair framing the sides and front of his face, consistently outfitted in a standard blue uniform with a belt and black boots. His personality merges boisterous joviality with a thread of underlying logic. He openly indulges in gambling, drinking, women, and pornographic art. Despite these tendencies, he exhibits sharp reasoning skills and a drive to solve mysteries—a curiosity that occasionally thrusts him into scenarios exceeding his expertise. Prior to joining the Quin Zaza, he wandered the globe alone as a solo traveler.
