The Demon Chronicles part 1

Heaven had made a deal with the seven sins that they would not kill humans and they would leave them alone only because they had tried to send angels down to stop the sins, but the sins were too powerful for the angels to be able to do anything.

The priest finds himself with an unexpected partner which destiny has other plans for. He finds himself in trouble many times but his belief of seeing his wife and daughter is the only thing that keeps him going. Will Heaven forgive his sins or are they just trying to use someone who must keep his belief that they will hold their part of the deal? Even I don't even know how this will end so I will walk this journey with you.
