Koujo Denka no Kateikyoushi

Despite being one of the most promising candidates, Allen fails the final exam for the position of royal court sorcerer, forcing him to abandon his ambitions and return home. Adding to his woes, he does not even have enough money for the train fare back, stranding him. With help from a former professor, Allen secures an unusual job offer: to be the private tutor of the daughter of Duke Howard, one of the kingdom's most powerful nobles.

The girl, Tina, however, has one critical flaw—she is completely unable to use magic. Though her academic prowess is nothing short of prodigious, intellect alone is not enough for the fast-approaching entrance exams to the prestigious Royal Academy. Moreover, countless magic instructors have tried to solve her problem and gave up in the process. To help Tina overcome her limitations, Allen must dig deeper into the roots of her magical inability, and, in doing so, uncover far more than he ever signed up for.
