A court magician, Clarissa, who is more than a flower, is caught in a high-class demon tool and secretly ordered to take care of Theodore, the leader of the Knights, for ten days in the basement. He is said to have been subjected to regressive magic for a certain treatment, and unfortunately, his spirit never returns at the age of nine.
