In this universe there are two groups, the ones who control life and the ones who control death. But there's a bit of a problem, controversy. Most people would say they are fine with there job or think that they're in the correct group of people but Danta doesn't think so. He feels sorrow everytime he is chosen to control the end of someones life. He only enjoys his job if someone seems to deserve it. But he finds someone that convinces him even more to try to join the life group.
