DEATHNOTE is totally mangu, I mean it's a Jump manga ffs (Naruto, Bleach, etc.)
It's fun though cause it's not a fighting manga or about a kid who wants to be TEH BEST at something.
The protagonist finds a shinigami's (death god's) notebook, a "DEATH NOTE," and discovers that the name of anyone he writes in it will die of a heart attack within a minute. He then starts TAKING OUT SOCIETY'S TRASH and trying to build a better world. Then the Japanese police and FBI start investigating him. Then hijinx ensue.
It's actually pretty interesting, because I can't remember the last anything (movie, book) I read where I like the guy on the run and the guys trying to catch him equally. Both sides/stories are super fun and because it's mangu every 24 pages it's IN YOUR FACE with the twisty plot action.
And yes, HBW is my favorite Murakami with a bullet.
