Knights Contract tells the story of the witch executioner Heinrich, who suffers a curse, and the young resurrected witch Gretchen. The story takes place in the sixteenth century of witch trials, a time when witches were something to be avoided.

The end of the world is approaching, and Gretchen, who has already died once, has no desire to see life end again. She decides to use the curse she placed on Heinrich before he killed her, and with him on her side, she fights the forces of darkness.

Of course, nothing is as simple as you think, and bloodshed is required for the world to be restored. Razor-sharp liars and explosive magic are your main weapons in a world where there is always someone nearby who wants to see you dead.
