Time is medieval. In this world of absolute class where the royal family (Legias) and the aristocrats (Aristo) compete for supremacy, there is a cruel reason that the master and servant are decided by the engraved brand. The jig used to kill many humans with its assassination technique according to the king's orders, but now he is ostensibly torturing and saving the innocent.

However, one day, he was involved in the plot of the royal family by saving the death row princess Alicia, who was killed for innocent charges.
