The first volume of "Yu Yu Hakusho" too little account of what you should expect from the series. Yusuke Urameshi is a troublemaker who avoids the death of a child, but ends up himself to the land of standing by. As his death was unexpected, they give you the alternative to make the resurrection of the test, and now he needs to show that it is a good person. The first volume is basically it, with Yusuke knowing several supernatural cases of spiritual guide Botan company and interacting distance of his schoolmates, the prissy Keiko and Kuwabara rival.
Although the manga seems a simple comedy, will be starting next volume that things will change figure: Yusuke will rise(spoiler king). And will work as a supernatural detective, caring for cases involving a lot of punches. Like any classic shonen obviously the clichés of training and fighting tournament are included.
But the grace of "Yu Yu Hakusho" is that the manga is less no-brainer that his countrymen's Shonen Jump magazine, as "Knights of the Zodiac" or "Dragon Ball". RPGs fan, Togashi always creates interesting powers for their characters and limitations that make each battle pretty much a game of chess for the fighters involved, without this be boring for the reader. The author might use this side of creation stories in a series published later in Japan, excellent "Hunter x Hunter".
In short; this is one of (if not the) best manga from the earth!
