Miguel, the judge of Life and Death

The story revolves around Miguel, a nerdy boy who has several defects in his life, but did not expect that some would happen to him, such as awakening a power where he could control the moments of another person's life when they reach the end of his life, Miguel controlling this power just to think about the person and imagine. But that ends up leaving Miguel with that uncontrollable power because he doesn't know how to control it. Miguel is sick and depressed because he thinks he is killing innocent people, until he discovers that it is actually the incarnation of an angel named Azrael.
