Yu Yu Hakusho S1E5 – “Yusuke’s Back”
Yusuke is told by Koenma that, in order to complete his resurrection, he must get someone who cares about him to kiss his body within one day, this being the conduit of his soul back into his body. As he was unable to convince Kuwabara and Atsuko, he manages to get Keiko to do so just in time. Yusuke witnesses Kuwabara falling victim to a gang leader who has kept his pet cat hostage. He catches sight of a demon after defeating the gang leader, as it turns out that Koenma has other plans for Yusuke now that he is alive again.
