Story by Ooba Tsugumi; art by Obata Takeshi (The mangaka of Hikaru no Go)

The human world is rotting. The gods of death are bored.

Death Note begins when the shinigami Ryuuku, 'accidentally' drops his death note in the human world. It is discovered by 17-year-old academic genius Yagami Raito, who decides that he wishes to create a world free of evil. To what extremes will he go, only needing a name and a face to kill? Or rather...how will he be stopped?

Overall:
It is a great anime I should say.Though probably not for those who prefer "fighting only" sort of things.Either way,there are two concepts of Justice and morality here so this is pretty much brain-melting if you think hard into it.However,most of the plot is dark and there is no humor content AT ALL.Well,unless you count L's personality into it or something.

Trivia:
-Note that this is adapted from the Manga so the Manga have much more content than the Anime version.So check out the Manga for the ENTIRE PLOT since the Anime is a fairly compressed version of the Manga.
-There is a film adapted for it,Death Note I and II and L changes the World.But this is even a much more compressed version :P But it's still pretty cool to watch.
