I know it starts a little bit boring, but I think it's part of the story build up, It is a story of a High school lad, Light Yagomi who finds a book, Death Note, in the field. It comes with rules on it and finds out when you write someone's name he/she can die. He uses it to punish the wrong doers in the society by death, but one thing comes in his way, detective L tasked with the job of finding the person killing people using the note book.
