A dude kills people with a book because there's a demon dude. And then there's a smart dude who figures out that the dude is killing people

If you like the detective, mistery and murder type of series then Death Note it's totally for you. I think I saw it a hundred times 'till now lol.

Thanks

There's this dude named Light Yagami and he thinks he can be the world's new god by killing criminals and people who try to find out who he is.
