Sousei Mahou no Saigensha

"You're a failure, don't ever cross my threshold again!"

In a country where magic is everything, especially in a kingdom where everything is determined by the ability of "bloodline magic" that only nobles are born with. Hermes, who was born as the second son of a certain noble family, was found to be a "failure" with no bloodline magic despite his high magical talent, and was exiled from the family. Hermes was almost killed in the depths of his disappointment, but then he was picked up by Rose, a "witch" he met, who saw his talent and made him her apprentice.
