Urameshi Yuusuke, 14 years of age, is about as troublesome and violent as teenagers come. He is constantly ditching school, causing uproar, 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 Yuusuke. The afterlife is not prepared for Yuusuke, as they never thought he would make such a sacrifice. Nowhere to go, and dead, Yuusuke becomes a ghost and must earn his way back into existence.

Yuusuke is "employed" by Koenma, who is in charge while his father and ruler of the afterlife, King Enma, is away. Under Koenma's command, Yuusuke 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.

Throughout Yuusuke'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, who 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!

Yusuke Urameshi is not exactly what you'd call an angel. In fact, some might call him down right devilish. But when he dies in an accident trying to save a child, he finds himself in the Spirit World. Unfortunately for Yusuke, his name is not listed in the Book of Enma, which means it was one big mistake! So he should return from the Spirit World, but must pass a few tests first, and become a detective of the spiritual world.

So now Yusuke works in the Spirit World as a half-dead, half-alive agent for Koenma, son of the ruler of the Spirit World. This position does have its disadvantages, especially when you're trying to enjoy your summer vacation and Koenma gets kidnapped! So now Yusuke must interrupt his summer fun to find Koenma and trade the Golden Seal of King Enma for his life. But if someone other then King Enma has the Golden Seal there will be chaos in the Spirit World! What's a half-dead spirit detective to do?

With the aide of his closest allies, Yusuke sets off for Magma Valley, to save the life of the one who saved his, and find out who's at the bottom of this evil conspiracy.

A four part OVA series including Yusuke's weird dreams.

Millennia ago, a war was fought between the Netherworld and the Spirit World. Ultimately, the Netherworld was destroyed and Lord Yakumo, the King of the Netherworld, was banished to the depths of space. Now, five defenders from the Spirit World must team-up against Yakumo's Demon-Gods for possession of five, mystical sites. But Lord Yakumo is dangerously close to reclaiming the Power Sphere—the source of the Netherworld's energy—and once it is again in his possession, our world will become the new Netherworld.

These are two recap specials that focus on Team Urameshi's matches in the Dark Tournament, with a few character songs playing in the background.

There are also two shorts at the end of each episode, both of which are about 1:20 long.

A special that acts as an epilogue to Yu Yu Hakusho, with the opening and ending songs from the anime interspersed throughout.

Eizou Hakusho II actually consists of four separate volumes. Each volume focuses around one of the main characters; Yusuke, Kurama, Hiei, or Kuwabara. Each episode is basically recap about the specific character's involvement in the series.

The beginning of each episode also contains a short music video about the specific character, with a song by its seiyuu.

Because the Demon World Tournament winner has requested it, Yusuke, Kuwabara and Kurama get together in front of an audience for each of them to record a morning and evening greeting.

The problem is how to get Hiei to do the same.

25th anniversary anime adapting the "Two Shot" bonus chapter from the manga's seventh volume, as well as the manga's penultimate chapter "All or Nothing." The "Two Shot" chapter tells the story of how Kurama and Hiei met, while "All or Nothing" shows the main characters reuniting to solve a hostage crisis in the spirit world.
