In the series "Death Note," the Shinigami eyes have a significant role as they allow the user to see the name and remaining lifespan of any person. By trading half of their remaining lifespan, a person can obtain the Shinigami eyes, giving them the ability to easily identify and kill their targets by simply looking at them. This power adds a layer of complexity to the moral dilemmas faced by the characters in the series, as they weigh the cost of using this supernatural ability against their own mortality.
