In an Utopian Society called Verciny, the government gives away 20 babies a year to a secret organization called Mors. The sacrifices lived in the labs their whole life and didn't know anything about the outside world or why they were tested. However all the subjects died only Miku, who was left alone with experiments with no reason to live. Will she survive or die like the rest?

I'm sorry I suck at writing summaries since I haven't finished it. But I'll try to make it sound understandable. This story revolves around 7 characters who have to fight against each other to gain what they want. Each person has one belief from the 7 Deadly Sins. IA (Jessica) has been an experiment ever since birth, her friends like her have all died and only she is left.
