Da Hell is Yu Yu Hakusho?

Not familiar with the Yu Yu Hakusho anime? No problem! What you need to know to fit in here is pretty simple, actually.

There is a....

Human World (the dimension where we live)

a...

Spirit World (where Prince Koenma, the son of the god King Yemma, has his castle from which he and his employee Ogre run things. It is also the dimension where the Angel Society, a city of angels, is for this site)

and a...

Demon World (the dimension where demons live, obviously. Not to be confused with Hell, which is a different dimension and relatively unimportant)
There are barriers which keep the demons out of Human World. After the series is over, the barrier was destroyed, in hopes a few responsible demons being picked on in Demon World could co-exist peacefully with humans.

90% of humans can't sense demon activity, a disguised demon, or someone possessed by a demon - any of that good stuff. Those who CAN are referred to as psychics, which is the category a few main characters fall into.

The SPIRIT DETECTIVE is a psychic who has an abnormal amount of spirit energy (fighting power, essentially) employed by Prince Koenma to basically police the demons and humans, making sure the demons don't get out of hand.




See? Wasn't that simple? You now know how this universe works!
