Thor once belonged to a hero’s party, but now he works as an ordinary teacher at Veren Magic University, where support magic is treated like a second-rate art. After defending his student Reina from trouble, he loses his position and is forced to leave the academy with no clear path ahead.

His next chance comes in the neighboring Neustade Empire, where Princess Elena unexpectedly appoints him as a court magician. Thor sees himself as nothing special, yet the magic he has spent years teaching carries far more weight than he realizes. With former students rising across the world and his own worth slowly coming to light, the dismissed support mage begins a new life that may prove stronger than anyone expected.
