This group of unlikely allies goes on to participate and struggle in battles that have outcomes that determine the fate of humanity! He is also joined by two demons named Hiei and Kurama, whom are ex-convicts of the afterlife that managed to escape from Koenma.
Throughout Yusuke’s journey, he is usually joined by his arch-rival, and local bully, Kuwabara Kazuma. Under Koenma’s command, Yusuke helps to stop menacing demons that threaten the lives of people everywhere whether by stealing priceless and invaluable items and destructive weapons, or by wreaking havoc on humans everywhere. Yusuke is “employed” by Koenma, who is in charge while his father and ruler of the afterlife, King Enma, is away. Nowhere to go, and dead, Yusuke becomes a ghost and must earn his way back into existence. The afterlife is not prepared for Yusuke, as they never thought he would make such a sacrifice. Such an action, was never ever expected, especially coming from someone as troublesome as Urameshi Yusuke.
One day however, he does the unexpected, sacrificing himself to save a young child. He is constantly ditching school, causing trouble, and getting into numerous fights everyday. Urameshi Yusuke, 14 years of age, is about as troublesome and violent as teenagers come.
