Shinigami (Death Note)
In the manga and anime series Death Note, Shinigami (死神?, literally "death god") are the race of extra-dimensional beings who survive by killing humans to extend their own lives. Shinigami in this series are not responsible for every death that occurs; people will eventually die regardless of whether or not the Shinigami pay attention to them, but a Shinigami can end their lives sooner than intended for their own benefit.
