Felice was born into a family of knights who, for generations, have guarded the Imperial Palace and the mages of the Murrer household. However, his extraordinary talent allowed him to become the youngest ever Grand Court Mage.

Meanwhile, Airis Murrer, who lost his Court Mage position to Felice, fell into an intense inferiority complex and began living in seclusion. Driven by his envy, Airis eventually curses himself with dark magic.

When Felice is asked by a childhood friend to lift the curse, he tracks down Airis. He is then told that to break the curse, sexual acts are required...

"Even the Grand Mage can't stop his nipples from becoming vulgar, can he?"
