If you are not a stable person, you shouldn't watch this Anime, cause there are a lot of scenes that are not safe to watch if you are. Let me take you into a world where the suicide law is discussed, you are allowed to kill yourself if you really don't want to live anymore. But what if the government doesn't know if it would be right to set this law in the world. Meet Zen and his coworkers that are entrusted with this law and to find out what is good and what is evil in this world. There are many brutally shots and brutal deathsin this Anime, I warned you already twice now.

Should a law like that exist, or would the world extiguish?
