Support magic, which boosts someone's abilities or, conversely, lowers an enemy's. Its derogatory name is "Babysitting Magic"──

Thor was a lecturer who taught this unpopular support magic at Veren Magic University.

One day, Thor helped a female student, Reina, who was being harassed by a male student.

However, the male student was the son of a noble family that sent large bribes to the university, and Thor was fired.

With no prospects for re-employment, Thor was given a letter of introduction by Reina and headed to the imperial capital of the Neu Stadt Empire, where he was hired as a court magician by Imperial Princess Elena.

Believing he lacked the ability to serve as a court magician, Thor underestimated himself. In reality, however, his support magic was the strongest in the world, and his students who had learned it had accomplished numerous great feats.

Thor was bewildered by his students who praised him, but...

"At the very least, I want to be cool in front of my students"──Thor encouraged himself with these words and unwittingly went on to excel with his world's strongest support magic.
