Ozaki is a human student at Myōjin University who commands significant popularity among female students due to his status as a prominent athlete. His physical appeal and social standing make him a central figure within the university setting. Amano Jyaku, a man-beast hybrid tasked with locating the prophesied Chōjin (Overfiend), initially identifies Ozaki as a potential candidate. This critical misidentification directly contributes to Ozaki's eventual demise. While Ozaki maintains a major presence in the original manga, his role in the animated adaptations is limited, appearing exclusively in the first volume of the original video animation (OVA) series. His storyline concludes following Amano Jyaku's error, with no documented narrative development, background expansion, or involvement in subsequent events, spin-offs, or later installments. His fate remains tied exclusively to this early story arc.
