The Hermes family has been producing excellent magicians. However, it was discovered that their third son, Frey, was only suited to the unpopular ice attribute in the modern era. As a result, Frey was looked down upon by those around him and was exiled from the Hermes family. "I'll show them... I'll become stronger," Frey declares, and he meets a lovely girl. However, she is none other than Arcelia, the Sage of Ice, one of the Seven Sages who saved the world. In order to become the world's strongest ice-attribute magician, Frey looks up to Arcelia as his master, but before long, his feelings change to love. He might even... propose?
