Mukuro is one of the Three Kings of Makai. She's been a sex slave since birth and on her 7th birthday she decided to pour acid on her body to have her master abandon her. Once free, she replaced the burned right side of her body with mechanical parts and masked herself to hide her womanly status. In the following centuries, she became more and more strong, feeding her powers with the hate derived from her traumatic childhood, and slowly built a kingdom until she became strong enough to face the Makai Lord Raizen and started a war against him. She was saved to be consumed by hatred by finding Hiei's lost Hirui stone, that had the power to calm her soul, and later she summoned Hiei to be her ally in the Three Kings war, and she developed a deep bond with him due to them having both experienced deep hate and traumatic childhood. During the Makai tournament in the anime, she fought Hiei and she won, but he managed to break the hard chains that she had on her wrists since the time of her slavery, a symbolic way to free her from her past. In the manga, Hiei does the same thing by capturing her abusive master and removing a mental conditioning that prevented her from trying to kill him.

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