Richette, a duke's daughter who possesses memories of her past life as the "Founder of Magic," is branded a "fake" due to her lack of magical power and is subsequently banished from the duke's household.

Left with nowhere to go and on the brink of death, she is saved by Crown Prince Lucius—a man feared as a "Calamity" because of his inability to control his own magic. In exchange for his protection, Richette decides to become his teacher.

This is a tale of magic and bonds, where two unwanted souls join together to rewrite their destinies.
