A life together started on a witch's whim. Witches who give and witches who take. In the time they spend together, what kind of changes will those who change bring to the witch who never changes? A collection of short stories about witches and the children and messengers they've found.

Which is the most terrifying thing in this world, devils or human nature? Legend has it that here lives a fearsome black witch and those who see her stand no chance of returning alive. The only child who survived pulled on Mesa’s hand. With eyes full of hatred for the world, he held her gaze and asked to break the contract. If this is how it is, I shall give you a new life, then. A story of a witch picking up an injured boy from the battlefield and raising him to be devoured. (Source: Libre, translated)
