Yu Yu Hakusho follows Yusuke Urameshi, a 14-year-old delinquent who dies saving a child from a car. Since nobody expected that good deed from him, the Spirit World offers him a way back to life, and he starts working as a Spirit Detective, tracking down demons who cause trouble in the human world. The cast falls into clear groups: Yusuke's team, with Kuwabara, Kurama and Hiei; the Spirit World staff, such as Botan and Koenma; his teacher Genkai and his friends from school; and each saga's villains, from the Toguro brothers to Sensui. This page covers 14 characters, with their Japanese voices and, where a source names them, the actors from the classic Brazilian Portuguese dub.
