Noble young ladies were often said to be either rude and ill-mannered, or hopeless airheads with nothing but flowers in their heads.

Even in an age filled with such rumors, there was someone who taught them.

A commoner named Derrick, who awakened to his talent for magic and rose to prominence as a mercenary, is one day invited to serve as a magic tutor for noble young ladies.

As Derrick proves himself a star instructor— turning spoiled aristocrats into proper “people”— prestigious noble families begin lining up with offers of their own.

“There are no bad noble ladies.”

At least, not in front of Derrick.

I possessed a third-rate extra villain character in my favorite game. I have no ambitions and I just want to live a quiet life. But sheesh, this world is a hard place to survive in. I will survive to the ending of this story, in a way the protagonist cannot. I will survive in the way of a third-rate villainous character.
