The story is based on a woman with a sense of dumb justice, she always wants to help others and ends up getting very bad and almost dying because of this, then because of a job of a driver's job that she took to earn more money, something went wrong and she got involved with the mafia, when she was going to be killed someone bought her, that someone was the owner of an exclusive restaurant for assassins, there we see several types of murderers which makes the story very interesting, but again the main character with his sense of justice even there wantsto help and do good things for others, which ends up causing her to be several times tortures by the murderers of the place and almost died in most of them but even then she does not learn and does the same thing again, which would be a negative point of the manga, but if we leave aside the main character and force the assassins we will have a reasonable story and that is able to entertain those who like a good gore, the killers have even good background stories, and remarkable personalities.

A good work on murderers and their diversities, contracts, rules of their world, if we ignore the main character is surely an incredible work.
