In the realm of Japanese folklore and popular culture, Shinigami are considered death gods or spirits that govern the cycle of life and death. In many portrayals, Shinigami are depicted as immortal beings who are not easily killed. However, in some interpretations, it is believed that a Shinigami can be killed if they break their own rules or go against the natural order of life and death. This act of defiance or violation of their duties can lead to their demise.
