Manga author Makoto Sanada’s blog has announced that their and Kudan Nazuka’s Angels of Death Episode.0 manga will end in four chapters. Sanada reported that the plot up to the last chapter was already submitted to their editor.

As a prison counselor, Daniel Dickens is no stranger to odd encounters with inmates. But when a particularly aggressive prisoner enters his office claiming that his session with a priest left him “fulfilled,” Danny, who has led an unsatisfying life, has to know more. During their meeting, Danny finds there’s little he can hide from this mysterious clergyman, and when an offer comes his way, he’ll have to make a decision that will change his life forever.
