Sometimes, fate manages our lives completely differently than we would like. Simple and so sweet revenge to the demon’s heart turns into a real punishment for himself.

Demons are not the kind of people to pass by gifts of fate, self-confidently thinking that they won’t have to pay for them. But sooner or later, Ariatar will need to understand who this strange child is: punishment or punishment. Or maybe... salvation?
