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".
