story in Weekly Shōnen Jump. Concepts The notebooks The core plot device of the story is the "Death Note" itself, a black notebook with instructions (known as "Rules of the Death Note") written on the inside. When used correctly, it allows anyone to commit a murder, knowing only the victim's name and face. According to the director of the live-action films, Shusuke Kaneko, "The idea of spirits living in words is an ancient Japanese concept.... In a way, it's a very Japanese story".

Obata said that he wanted to draw the story after he heard of a "horror story featuring shinigami". According to Obata, when he first received the rough draft created by Ohba, he "didn't really get it" at first, and he wanted to work on the project due to the presence of shinigami and because the work "was dark". He also said he wondered about the progression of the plot as he read the thumbnails, and if Jump readers would enjoy reading the comic. Obata said that while there is little action and the
