Yusuke Urameshi (浦飯 幽助, Urameshi Yūsuke) (also known as Eugene in the Filipino dub) is the main protagonist of the manga and anime series YuYu Hakusho. He is a Spirit Detective who is tasked with protecting Human World from various supernatural threats over the course of the series and his closest friends as well as greatest allies include Kuwabara, Kurama, Hiei, Keiko, Genkai, Koenma and Botan. He is also the de facto leader of Team Urameshi and the general person to look to when the going gets tough.

At the start of the series, Yusuke is an uncontrollable teenage delinquent/street fighter with little to no positive qualities to his character. Over the course of the series, he starts becoming a better person, changing into an almost altruistic defender of the Human World.

He wears a green jumpsuit with gold buttons and black shoes (a substitute for the blue school uniform he should be wearing). At the Dark Tournament, he wears a red jacket (with yellow tinted cuffs and collar) over a white shirt, along with pale blue jeans and white sneakers. When actually fighting, he switches to a yellow sleeveless shirt and blue pants, with black shoes, a black karate belt and green wristbands. At the beginning of the Chapter Black arc, he wears his red jacket look, replacing it with a dark green suit jacket. In his fight against Sensui, he was seen without the green suit jacket as his white shirt that he wears was now loose. During the final arc, he returns to the complete red jacket look. During his training with Hokushin and being given his inheritance by Raizen before dying, he wears the same outfit as in the Dark Tournament; his sleeveless shirt became light yellow and his black karate belt is replaced with a black obi and his blue martial arts pants became longer due to his current height. When fighting in the tournament, dons a fully white-clad karate uniform, complete with a green sash around the waist and black shoes. He is also seen wearing a complete dark blue suit with grey pants, black shoes and a white undershirt when visiting Kuroko Sanada
