Shinigami (死神) are spirits of people who committed suicide. They are responsible for collecting the souls of humans who are approaching death. When a human commits suicide he or she is reborn in the underworld as a Shinigami. Their first memories as shinigami are usually that of lying in a cracked eggshell, with little satisfaction and a feeling of emptiness.
- In episode 2 of the anime, Takuto comments that Shinigami have the power of transformation.
- In episode 49, Izumi mentions the possible reason why Shinigami turn into ghosts. It is that they are still linked to the human world.
