Koujo Denka no Kateikyoushi

Allen fails the final examination for his dream position at the royal court and plans to retreat to a simple life, only to discover he cannot even afford the trip home. His temporary solution is a job from Duke Howard: tutor the duke's daughter Tina, a brilliant student who somehow cannot cast magic no matter how hard she tries.

Rather than repeat the teaching methods that have already failed her, Allen studies the way Tina's magic behaves and realizes the problem is not a lack of talent. His unconventional lessons draw him deeper into a noble household surrounded by political tension and unusual abilities. The tutoring job he accepted out of necessity becomes a chance to prove that his real gift may not be the court position he lost, but seeing potential everyone else overlooks.
