Yoko Togashi

The YuYu Hakusho manga series features a diverse cast of characters created by Yoshihiro Togashi. It follows a fourteen-year-old junior high school delinquent Yusuke Urameshi, who dies but is resurrected to become the Underworld's detective of paranormal events in the Human World. He begins his work in the Human World, but ends up traveling to the Underworld and then eventually to the Demon Plane. In each case he undertakes, Yusuke meets several new enemies and allies. Other predominant characters include Yusuke's rival delinquent Kazuma Kuwabara, the fox demon Kurama, and the sword-wielding fire demon Hiei. While several characters are humans, many are demons, and both have different supernatural abilities due to harnessing their Reiki, one's own aura or life energy.
